Why do you want a set of fuelie 460 heads? the only upgrade possible is very minor and thats putting on the F3TE heads and I hear it's not all that much of an upgrade at all.
So do you have a cracked one or something?
Those are off a 460? I pulled them off of my 88 351W. I have a cracked one, not sure if the other one is good, can't see any visual damage but with my luck lately it'll be bad.
What head numbers will fit my engine?
