318 cylinder head upgrade

If I were building a “mild” 318(call it “around 300hp”), and the core motor I was going use had them on it already, and they weren’t cracked, I’d probably use them.
But it would be pretty much the same case for just about any 318 heads that were on it.

If I wanted to try and “make some power”........ I’d use heads that had higher ootb flow numbers as a starting point.
