[MetalHead]

Are a set of Cleveland heads too big for a 289 engine with mods? I have a chance to get a free set of Cleveland heads, but those were meant for an engine that is considerably bigger than mine. Are they even compatible? If so, what problems should I forsee happening if I try to bolt them on? I also have a chance to get a pair 302 heads, would those be better for my car? I was thinking about just taking the 302 heads and have them bored out and port polished. I'm in the process of putting in a toploader or T5 tranny, after that I'm going to get a new differential, 8.8 with 3.55 or 3.73.

Given this configuration, what would you do?

Thanks alot,
Jason
