True...

The 392 Ford crate engine used the GT40X heads, which are not known for their performance offerings. The OP could gain about 70-75 hp alone from a head swap. Plus, when you add air flow, it's easier for the camshaft to work, then you get a higher hp peak as well. Kind of a two-fer.

It wouldn't be prudent to *try* to snag 70 hp out of a camshaft swap. You'd end up with a fussy engine that had no bottom end and no top end either, due to the heads hindering the cam's ability.
