I've been looking at the Pro Lightening heads fro Pro Topline and they seem like a great head. Good low lift numbers.They 180cc intake runners and 64cc combustion chambers. I'm already going with the LPE 211 cam and think it would match up great. Anyone have experience with them?

Guess not to many people here run em.

I like them...check out their website and then call around to some of the dealers in the US...

I got mine from Competition Products...I bought them bare and put together a valvetrain kit from them too...

They are capable of big power for less $$$ than AFR's...

I paid about $1160 total including parts, having my head guy assemble them for me...with decent springs, PC seals, etc.

Also, when the search function comes back online, there are a few long threads about them...

FYI

We flowbenched a set of the 220cc heads here at work. They flowed almost the same as my AFR 195cc heads did, about 5cfm less. While it does seem rather silly that such a huge chamber flows only equal to the much smaller chambers of the AFR heads, you can still pick up the Pro 220cc heads for chunk less $$$ than the AFRs. I feel that the AFR is still a better cylinder head, but it's up to you to determine whether the price of admission is worth it.

I was also thinking of these heads for my next engine. They seem to flow huge numbers for a relatively cheap price. On this website http://www.lmengines.com/ProActionmain.htm they state that they flow 264cmf intake @ .500 lift.

I was wondering about those flow numbers. Whether or not they are accurate? My price range is about where the Pro Lightning heads are. I'm either going with these or Trick Flow.

They goota be the best racing heads in the world!!! They're made in New Zealand MATE!!!:lala: :lala: :lala:

Call the dealers...their are a lot of circle track guys who like these heads because they perform well for the price...

As for the flow #'s...there is a thread out there somewhere (when the search function comes back) where someone flowed them and they flowed pretty damn close to advertised...

I also got the CNC chamber option which may help the flow #'s a little bit...

If you are looking at the cast iron heads, I would say go for it...

HOWEVER, you also don't state what kind of engine this is and what complementary parts you are looking at (size, cam, trans, gears, intake, exhaust)...so choosing an intake runner size is a bit tougher to do...

Brad

Don't get me wrong, I never said they flowed less than advertised. It's just that they advertise flow numbers which are much lower per intake cc than the AFRs. I think the heads are great budget heads, I do not have anything bad to say about them. I just don't want people thinking that they are absolutely better than AFRs. The AFR is a better head, but not necessarily a more cost effective one. With 260-270+ cfm flow, cylinder heads have the potential to make great power, no matter what the brand is.

88TPI406GTA

There have been a few people who have flowed their AFR heads and they have come up a bit less than advertised...not much less, but a bit less nonetheless..

I wanted a head that could grow with my 406 for the future and that would offer the same flow as the AFR 195...for me, that is the 220cc aluminum Pro Lightning head...

I was skeptical at first too because AFR is the most established "best choice" head out there...but after talking to a lot of different shops around the US to find out how the heads actually perform, I decided that for the same flow potential, the Pro Lightning head is a better deal...

I have a pretty mild cam right now with my stockish-type shortblock, but I realize that it helps to offset the large 220cc intake runner of the head...I may be losing some torque, but I have more than enough to sacrifice a bit right now...

The key is that I only wanted to buy ONE set of heads for now and the future....I want 550 HP NA and fairly streetable in the future with a 406...

I will probably end up going with these heads. I was just wondering if I should go with the 180cc or 200cc intake runners. I will be running a 350 with the holley stealth ram, not sure what cam but something in the range of the LT4 Hot Cam (218/228 .525/.525 @ 0.50).

88TPI406GTA

I would think that with the Stealth Ram, 200cc heads, a cam with a bit more duration (think XE268, except with 114 LSA) and 1 5/8" headers and free flowing exhaust...that would be a pretty decent deal...

With prom tuning of course

What about the Aluminum 180cc heads. I was thinking of going with these since I'm running a modified LTR setup(SLP runners,accel base) and 211 cam. The guy at Proshaver told me that they have raised intake ports? Wondering if they would work for my applicaton(other than no EGR)?

88TPI406GTA

I think you need to check out the proline website and get the right part # yourself...

My 220cc heads do not have raised intake ports...it depends on how you order them...

JR305...Have you had you car on the 1/4 mile...interested coz I'm setting up the same sorta thing at the mo, what HP you gettin?

S10Wildside

I've got a set of 200cc on my motor. I purchased them from Summit for under $600 shipped. I got the bare castings and had a machine shop get valves, springs, etc. They also strongly recommended these heads. Biggest bang for the buck. I'll have the motor running in a few weeks.

JR305

Kiwi-85IROC... I never got the car running right. A few weeks ago I dropped a Torque Bit into the TBI with out noticing it. Started the car up and the next thing I know I am hearing little pops and notice that the sparkplug to my #8 cylinder had sever damage to it. Pull the head and the piston has a bunch of little imprints in it. But had I gotten it running correctly I think it would have been a mid 13s car NA.

S10Wildside... How much did it cost you once you got the heads completely assembled?


Does anyone know how much hp you can theoretically make with a given cylinder head CMF?

Kiwi-85IROC

Hehe JR305, I've completely destroyed a motor dropping a bolt down the carb so I know how ya feel !!!

S10Wildside

I think I paid just about $580 for the set of heads, and looking at my receipt from the machine shop, about $300 for valves, pushrods, valve locks, springs, valve locks, and a little work to smooth out a few spots on the heads. I don't know the details about the "pocket porting". After buying the heads and having them assembled, I paid less than what a set of AFR heads cost. And I have better springs than what you'd get from AFR.
