i got a crane powermax solid cam with 238*/248* @ .050 .480"/.500" on a 114lsa. with my 113casting aluminum vette heads with a mild bowl blend job and un-touched runners the car has gone 12.16@110mph with a lazy 1.65 60' time. (had to go easy out of the hole for fear of wheelhopping).

i'm thinking of going to a dart iron eagle head with 200cc intake runners. the car is my daily and i'm a little concerned about lowend torque, though as soon as i can come up with a little extra cash, i'll be buying a beater to get good mileage and such.

c/r with the 58cc aluminum heads is 10.2:1.

i'm thinking of going with the 64cc combustion chamber, which would effectively lower my c/r with the current head gasket (.041" corteco gaskets) to 9.5:1, but they are iron heads.

tell me the pros/cons of this decision...what would you do with no more than an $850 budget for cylinder heads?

oh yes, i want to spray it at some point in the future...after the daily status is revoked.

 

I ran 9.9:1 on pump gas with Vortec heads. I say whatever you get, don't drop compression, and you definitely could use more cylinder head. Just be sure to do some work to the Darts, they are a joke out of the box. My 220's and two of my friends' 230's were 30-40 cfm below dart's advertised numbers out of the box. Ridiculous...

 

what if i went to a .025" steel head gasket to keep compression ratio up...would it work well on the street? or maybe had them shaved down a bit...something around say 60cc combustion chamber...

and dad is running these heads on his car right outta the box...a little more cam and c/r (10.5:1) with a powerglide and 100lbs. more in the car went 11.78@118mph

 

My friend's 230's didn't even flow 170 on the exhaust at .700, on the intake they flowed 26X or 27X. Well below 300/2XX that they advertise on their website. Your dad probably has 2 or 3 tenths and mph if he gets some good porting done.

I am not really sure when it comes to street cars and head gaskets, I ran a .015" shim gasket to get my compression up with a 4v relief dish in a 350. I think dart sells a 54 cc version of their heads, might be worth looking at so you don't have to spend a bunch of money having your heads milled.

 

whatever i get i plan to do some cleaning up on them, but i don't want to have to hog them out...just clean up casting flash and stuff.

 

Yes with that cam 200CC heads would be better. Heck I'm using Dart PRO One's 200CC and my cam will only be a bady cam at 218* on the intake. With some searching you can probably find a deal on some used heads.
