440 engine ID pad help

What 440 is not hp? Even the 78 440 was the highest performing engine Chrysler had that year.
All 440s either had a 4 bbl or a 6 pac just like all 340s.

You engine should have closed chamber big valve heads. (915s w/2.08 intakes)

The research I did shows it has smaller exhaust valves than the HP version of the engine. And a different casting number on the heads.
