My buddy who does the port work is about to finish his move to NC. He has a set of assembled, not ported, GT40P heads and an Exploder upper and lower intake manifold in storage that he doesn't want to haul to NC.
Anyone interested?

Are these the "good ones" that you would consider to be the one to get if you were doing an efi conversion?

They are GT40Ps so they have a smaller combustion chamber than GT40s. This should translate to a very modest increase in HP over GT40s. However, they will require Bronco Hut headers to work due to spark plug angle.
Personally, I chose to go with GT40s for the following reasons.
1) I got a set of ported heads for free.
2) Even without the free heads, I was willing to sacrifice a little HP to save money on new headers. Mostly because I'm a cheap S.O.B.

Thanks for the mini tutorial. I know there is a lot more to it (efi) but this looks like a good start...I'm cheap too! Being a cheapskate means the Header thing would kill it for me.
Thanks

If your efi is a h.o motor you will need to replace the springs on gt40p heads but not the gt40 ones.I am waiting for some one to post some gt40's
