315 hemi core on craigslist

So how do you determine what a "gen 1" hemi is when all three designs were different?

A 315 is a Dodge not a Chrysler. And that has Poly heads...moron.
Early HEMI engines could swap heads with the Poly’s.

Piston valve reliefs were a n different spots. The HEMI has opposed to each other and the Poly being off set.

THAT engine is a HEMI via the valve reliefs seen.
