Thanks Don.

Curious as whether they are open or closed chamber. Any pics of the bottom side?

Sure.

So, assuming they haven't been worked, these would be the first experimental open chamber heads I guess...

Could be. Chambers look fairly uniform.

Thanks everyone!

On the way home from the Camaro Nationals my brother and I stopped at a fellow NCRS member's shop and took a tour --- he has an 0- aluminum block from Jim Hall's shop which he picked up prior to 1969 as a badly beat up engine- I noticed that it has an external passage for dry sump or mains priority lubrication.
Block was hurt but mostly fixed, needed the lifter bores for 7 and 8 milled and bushed plus 7 and 8 dry liners installed.
The gentleman also has the CE ZL1 from the Lemans Blue Sport Chevrolet ZL1.
