I thought these heads might be worth something but I’m not sure. I’ve read detonation issue and also with a little porting they flow great. I see they are a half year and early open chamber but the chamber only lasted for this head, correct?

Yep. Used to have a set of those. Oddball head/chamber. In `68 they had their open chamber figured out.
