(if u port) PI - High comp, good for N/A or Nitrous, but you gotta be careful about boost

(if you port) NPI - Good for boost because it doesn't affect compression ratio

well like i said, you could just blend the combustion chamber to drop your c/r if you wanted to run a blower, i would say you should have it done anyways, just not a lot to help un shroud the intake valve to allow for better flow but keep your c/r high. either way its going to be higher than what you already have.

is worth putting on the PI Heads and using the PI Intake or what do you think about Trick Flow Track Heat Intake Manifolds ?

I saw a full bolt-on, cammed 2v at hi-tech motorsports that made 312hp with a stock pi intake and 304hp with the P-51. Not only did it lose low-mid end power, it also lost peak hp. I certainly wasn't impressed by the P-51.
