Guys,I have finally given up on the project.One block has been sitting in MI since the COVID deal started.The only firm bid for machining was way more than I could have bought a modern alu block for.I had no intentions of building a hemi so decided to give them up to someone that does. I have sold them to gentleman in WY who is on a mission to build a hemi pontiac for a project.Stanup guy,check came over night and I suggested he post on this site wanting to buy a set of heads.Anyone on here that can help would be great for our hobby. Tom

Thanks for the update Tom.
It was super cool that you tried to make a go at it.

Good luck and best wishes to the man in WY with his plans.
