No parts here, but I have a good friend who is a Pontiac guy. Also, a very talented Ford engineer that I know is a closet Pontiac guy, bought a 64 GTO when he was fresh out of college. Pontiac bore spacing and FE bore spacing is very close, 4.625" I think for the Pontiac, and of course 4.630" for the FE. An FE head will physically bolt onto a Pontiac block, and 9 of the 10 head bolts will line up and thread in. My Ford engineer pal wants to put SOHC heads on a Pontiac block, and figure out a way to convert the rest of the parts to work.
