Should I keep these heads?

The Engle I got two years ago now was perfect, but it was a full custom grind I spec'd. I don't know who grinds Hughes now, but I liked talking with Mark Engle. I believe this was after the father passed. But I could be mistaken. The Hughes I still have I got on thier fire sale section of the web site like 9 years ago now.

Commando - I owned a '66 S car, with a 340 and stick. It had the 68-71 Hipo 340 manifolds on it and they fit perfectly. I've only had one, and I didnt do the install, but I know mine fit fine...
