If you like the gt40 p the BBK 1515 headers fit them and arnt that expensive. I have gt40p heads on my bronco and the headers clear with more then enough room to not burn the wires.

I prefer the P's due to the combustion chambers.

i prefer the P's cause they flow the same as the 40's but with smaller valves= velocity

So if you had 18psi through a 76mm turbo, which would make more power? Smaller valves with more velocity, or bigger valves that allow for more air?

And would the more velocity hold true if diversion is being created?
