I'm wondering if there are somethings I have to conseder before selecting the heads.
Anyone who built engines will tell me the best choice but I want to know why and how he knows that the heads he chosen are the best.? how he knows the best specs ?
that's my question... ( how Do you know the best cylinder heads for your project.?? )

just kidding but for my build I do know that I wanted power from 2k-7k and looking across at head choices I looked at AFR 205's and seemed that after 4k the heads unleashed the furry when it came to hp increases so I chose to go with them and had my cam spec'd to my heads along with related mods, example exhaust/power adders ect. Im learning everyday with my buddy who has done numerous builds and always asking questions which I think he gets pissed for having to explain himself, but hell with it, I just buy him beer Last edited by SkylarkLS1; Apr 8, 2009 at 03:58 AM.

Short answer is NO. You will hear lots of flowbench number claims that dispute this advice, however. Try not to choose based on "velocity" and "CFM" numbers.
Choose a very good and respected engine builder like Eric (racer7088) who has built engines that make great torque, power and perform well in actual vehicles on the road and track. If you have him build you an engine he will recommend/choose appropriate heads. If you are going to build it yourself, search for his posts about heads he uses. Buying them from him would be a thought.
There are other good sources of information and heads, but they don't necessarily hang out here.
Your goals and budget for your engine are very important considerations. Have those in mind when you start searching.
Caveat emptor!
