Choosing heads and a cam....any comparisons?
Choosing heads and a cam....any comparisons? I am thinking about also buying heads with a cam. So obviously flow numbers are very important. I am thinking of making a spreadsheet with all the different head makers and their offerings to start seeing who flows the best. As well as factor in the price.
Is there anyone who has already done this or should I start on this?
It's hard to decide when you don't see all the info right in front of you for all makers.

Add to that the fact that many give erroneous numbers on their flow and intake port volume, and basically you'll be wasting your time. It's hard to decide what ones to go with. You'd probably have better luck deciding how much money you can afford to spend, then seeing what heads are in your price range.

Wow you can be negitive.... I wouldn't go as far as saying the companies give erroneous numbers. They might flow their heads on different benches but I am sure they don't just add numbers for the hell of it. There are a lot more things to consider than just flow numbers though and some searching on this website will give you ALL the information you would possibly need to make a very educated decision.
how aggressive do you want to go? check out www.gtp-racing.com i have their stage 2+ heads as you can see in the sig. they work awesome and i have some close up pics of my heads if you'd like to see them.
my first heads/cam combo were those heads and a TR 230/236 590/598 112 cam and made 414 on a mustang dyno.. dunno what those figures would be on a dyno jet. i had my pistons fly cut and slapped that T Rex in there and put down 463/402 on the same stang dyno...so once again how radical do you want to go? lol

the closest thing to that is the Flow thread that Tony Mamo started, same bench, bore and operator. obviously the names are left out but you can a tell few if you know what to look for. and as stated there's alot more to look at then just flow numbers.

interesting, I was hoping that flow numbers would be a good way to compare with board searching to back up the rest of my research. Guess back to the search it is!
My goals would be to make over 400 hp, so I don't imagine I'd need a crazy aggressive cam or super awesome heads.

If that's all you want you can get some cheaper cnced ls6 heads and a proven cam. Just think ahead though because enough is NEVER enough....
Yup. That's why I'm on my 2nd h/c setup. I wanted 400hp on my first, and I got it. Then a few months later swapped them out for bigger and better. Just go big or you'll regret it.
i made 400 rwhp cam only so i would think you'd easily be over 400 hp h/c. i agree with N4cer...just got big. i had a healthy h/c setup at first but literally 3 months later i was swapping out to the T Rex.

off the top of my head 236/238 .601/.60? 113+3. I think the torque picked up from previous mostly from porting the fast and the Meziere. As soon as I have the rear and gears I am going bigger again on cam number 3!
