Hello Guys/Gals,
I am going to finally take the plunge. I have decided on some AFR 190 Street/Strip Heads for my 89 vette. They are gonna run me 1576.00 + shipping. I think that is kinda steep, but have been literally waking up for several mornings thinking about them......Sick huh. But don't you just love this stuff! Do you guys have any last minute advise for me? I would love to hear some success stories to further fuel my desires. I will also be looking to get rid of my Aluminum L98 heads that are currently on the car. They are in excellent shape and only have 38k on them! Yes I never really drive the car. My women says I spend more time cleaning it than I do driving it. I woould almost have to agree. I hope that I did not break any rules by mentioning that the heads will be available. I will say no more, you know how to get ahold of me if your interested. Thanks and I look forward to hearing your stories. Later

I am interested in the heads. E-mail me and let me know a price and time the heads will be off. Jr_4444@Hotmail.com

Get the large CC (72cc or 74cc) combustion chambers and have them milled to whatever chamber size you want. AFR is one of the few head makers that actually use 2 different castings, 1 for the 64cc and 1 for the 72-74cc heads. The larger chamber unshrouds the valves.

I have the 190's as does a friend of mine. They're great. I wouldn't have bought any other head. BTW, I'll take that 509 Merlin off your hands for $1576.00 + shipping, just so you won't sweat the AFR's

I have 195's on my Z,and my buddy has 190's on his GTA.I also got 72cc and had them milled down to 64cc as mentioned earlier.I wouldn't have bought any other head and helped convince my buddy to go with AFR.He has thanked me many times over.Only thing I can really say to help your decision is "Buy the damn heads aready"! Hope this helps

Can someone explain what unshrouding the valves do? Thanks

ski_dwn_it

Head have been ordered!!!!!!! I am pumped up!!!!!!! Thanks all. Anyone wanting my l98 heads email me. we can discuss details. Thanks. I will also have the intake and manifold to the car available. Haven't even given price a thought yet. Reach me if interested.

I wish you guyz would let me know before you purchase the afr heads! I could have saved you a few hundred bucks via my contact!

ski_dwn_it

Craig,
You are correct!!! I took your advice and called the other people. They were 1375.00 shipped to PA. I added another 50.00 to the guy because he did not want to use a credit card for the purchase???? He wanted a cashiers check. So we settled at that. They would have only been 1325.00 shipped!!!! Thanks Craige. I have a quick question. I ordered the same ones you did. Should they be milled down to stay with the stock 58cc, the ones I ordered are 68cc. Please advise on this before it is too late. Thanks guys.

Jesse,

I emailed you an hr ago. Anyway, If you mill the heads to the size chamber you want, go with the larger cc heads. Because the chambers are opened up more, Once the milling is finished you will have a more open combustion chamber. I think AFR will charge a fee to have this done. If you are running a blower, i would not worry about the difference in size. If you are normal aspirated and a 305...Then i would have the heads milled! Good luck!

ski_dwn_it

The heads are for my 350. So the 68cc should be alright? Boy I hope so. I don't want any surprises. Thanks again Craig!

My 350 is going to have 9.3/1 compression. I have .003 @ TDC from the piston to deck clearance. A frined of mine figured out my compression. Anyway, with that compression and my cam @.50 210\222 with 505\535 lift @ ll2 lca, AFR stated that i should be running between 430-450 hp at the fly without the blower I am running the same heads I belive 1022's?

Unshrouding the valves means moving them farther away from the sides of the chambers and farther from eachother so that the air/fuel mixture has more room to move into the cylinder and can keep moving a speed to keep the mixture a mixture!

Hey guys,
well I think I have it pretty well straightened out now. They are gonna shape the heads down to the 58cc that they are stock. This will leave the compression were it was at stock. This should be what I need. What kinds of HP do you think I will be cranking at the flywheel with my setup.

190AFR heads..LPE219 cam....Super Ram....Hooker Long Tudes (ceramic coated)..Accell Base...

Oh I can not wait...Its gonna be such a long winter..but it will be like getting a new car..then nect summer I may go with a 383 or 396 stroker!! That should make things even more interesting.. let me know what you think. Thanks

Jesse,

check out the AFR web site I think it is www.airflowresearch.com my combo should yeild 430-450 at the fly and its right inbetween the two 350's compared the only difference is the cam. I would say you will be in the same area if not more with the superram.

BuckeyeROC

You WILL like this combo!!!
BTW, my heads are 58cc too. I think stock was 64 or 68 cc. I have around 10.1:1 compression with the pistons I have.

watch those combustion chamber sizes when you stroke an engine...Because of the larger swept volume, what might be 10:1 on a 350 could be much higher on a 383-396... just my $.02

boyis this an old post. anyway, Ihave a few questions. I just ordered AFR 195 heads with the 72CC. These will be put on my 350. What will my compression ratio be with the 72cc. I may be puching it out .030 over. I plan to run nitrous on this engine on occasion and the car will be drivin on the street. cam will be the LPE 219 cam. mods are in sig. someone guide my in the right direction on how much t mill these heads

camarojoe

Damn, did you did this post out of its grave. How come you didn't post your own q? I guess it doesn't matter. If you're using stock pistons and don't get the block decked you'll probably go down a full point or more. 8:1 is too low for the street. You should shoot for 10-10.5:1. You're going to have to get those heads milled and make sure you zero deck the block, these are two musts.

quickL98

iTrader: (2)

got'em and love'em i was sold when my friend went from 8.40's to 7.60's then after more tuning and seat time eventually 7.30's with a set of out of the box 190's

BOTTLEDZ28

iTrader: (9)

but if I zero deck the block then doesnt that mean that ihave to have the intake milled too. Im trying to do this engine on a budget...yes I know AFR heads are not budget heads but there is always exceptions now what happens to the push rods when you start milling heads and stuff. do you have to get custom pushrods

AllGoNoShow

I wouldn't zero deck the block , I would leave the pistons about .010 in the hole so that there is enough material left over to deck the block again in the future....combine this with a .028 GM Composition Head Gasket and you will be sitting pretty at .038 Quench.

camarojoe

Decking the block won't affect anything at all regarding the intake. I don't like the idea of running thin head gaskets, that's why I would recommend the zero deck. Also, having the piston come up all the way up to the top will let you run more timing without detonation, it's more efficient to deck the block.

jim91z

If the deck height is lower, then the heads will be lower and slightly closer together, so wouldn't that cause misalignment of the intake ports and bolt holes?

BOTTLEDZ28

iTrader: (9)

thats what I was thinking.

EvilCartman

iTrader: (1)

The shop should be shaving a bit off the intake surfaces to get things aligned right.

OMINOUS_87

Have the block cut down to 9.005. Always leave .005 of meat for piston variance for a rule of thumb if you have unkown pistons, check for proper procedure though in the info that comes with the slugs if you have it. Most all pistons are advertised for their compression ratio at zero deck height and a .039 gasket. The directions with the pistons will tell you how obtain a zero deck height, zero deck has nothing to do with a 9.000 deck measurement. With different pistons 9.005, 9.010. 9.000 can yield zero deck depending on the brand of piston.

Clear as mud?

But whatever you do dont run anything more than .050 quench, that would be a bad thing on a new buildup. .035 quench is a bare minimum, .040 is perfect.

The whole reason the factory runs thin gaskets, .015-.026, depending on application is because they dont deck blocks out of the factory, yes i pointed out the obvious. But they never run over .050 total quench either

OMINOUS_87

Dont skimp on machine work, it will make or break you, details matter.

Square deck to zero deck height and TQ-Plate hone th bores. The line hone isnt needed if mains measure out, save a couple bucks there.

Shoot for ~10.25:1. Gasket match all your parts.

etc, etc, etc...

Here is some good reading to see how it all adds up.
