Yenko 3946074 aluminum heads?

Does anybody have information on sets of 3946074 aluminum heads with the yenko logo on them like I have seen on the aluminum blocks? What are a set of NOS ones rebuilt but never ran worth? I thought they were all the same but I found a guy who claims to have a set from Don Yenko himself?

Nope, never heard of them with the Yenko logo. If they have the 074 casting number on them, they should be GM.

Yes, there were some heads like that. I have paperwork on them which will be in my new book " The Yenko Era ....Continued. Canonsburg and Beyond." Which is overdue ! Been having trouble getting print quality on old documents. Hope to be available soon !

What would those be worth? This guy wants a lot of money for these heads and I have never heard or even seen these before.

I'm guessing he's asking $5k...if I were building the L-88 for the '75 Yenko T/A again, I would spend the money on them.
