pre 87 305 heads

Hey general question here, would pre-87 non centerbolt heads fit a 91 350 block that currently has centerbolt 305 heads?

'87 was the year for the switch. Check combustion chamber size on those heads. I think they're 58cc's or something. With flattops that's about 12 or 14 point. I don't know for sure, but that's getting into some pretty high territory. Be careful.
