The deck height is different between the small block and big block engines. Yes the heads share the same bolt dimensions.

1968-1972 should innerchange as far as the frame is concerned.

In theory you could install big block headers on your small block, though they would hang extremly low below the frame.

In no way could you put small block headers on a big block. They'll touch the lower block before you could get them bolted down. The starter would never fit.

Tell us exactly where the fitment problems are.
