and after reading this one should learn that a well match engine combo will go a long way, just do a lil research and take your time on an engine build even if it means waiting to get the etra money to get the best parts way better to do it right the first time thats how you save money in the long run!
As for cylinder heads there are a few great heads out there and a few average heads and alot of junk. will not name them most already know who they are if you have read any amount of forums or threads.
With that said if you are truelly looking for a great head and a reasonable price you will not go wrong with a set of profilers.
Have a set on my roller 406 after looking into a set myself hard to beat the flow and pinch on these heads are so nice theyll rival any AFR you match them up to.
I noticed you mentioned them, truely a great head and awesome castings aswell.
