they are one year heads. 1970 455 h.o. they only went into grand prix's and gto's. rated at 365 hp in the goat and 370 in the grand prix.
the small valve issue solves that problem. i've got a 76 cast iron intake but i think mr. p-body told me it won't work on the older blocks but i'll double check that. there is cast iron intake for sale locally. i may slap an xe 256 in it and i'll definietely get a smaller carb.
my plan is to use that torker intake, the 64 head and the big carb on a 400. i'm just waiting for the right block to come along.
for now i want to drive this car while the weather is nice. that's why the 350 is going in for now.
i've had this car for a month and haven't been able to drive it.
