RE: GT40
Alot of people hate the P heads but alot of guys love em. I've seen alot of buys go over the 300rwhp mark with P heads, they are overall a better head than the gt40. But you run into problems with the headers and plugs, kindof a pain, and a very small choice for headers.

RE: GT40
I've seen some tests w/ RHS heads and they are good heads, but aren't they more expensive? I may not be remembering correctly.....They are iron though, so you won't shave 60#'s of the front end w/ them......

RE: GT40
I agree that the gt-40p is an excellent head and is capable of making some serious RWHP. You stick larger valves in them and do alittle port work and your flowing right up there with alot of the aftermarket iron heads. As for the RHS heads, they are available in both iron and aluminum and are usually alittle more than the Trick flows ( but are better quailty castings IMO) but cheaper than the AFR's. Check out the link below for more info on the RHS heads.
