I think I got one of very last batch of that head. The maker is designing a new head that looks stock, has all stock mounting points but will have a better combustion chamber and higher compression, sort of a stealth head for the flattie. The intake is a reproduction (continuation?) of the original Thickstun casting. A batch pops up on Ebay every so often. Both the head and intake are cast and machined in the USA too.
If you are patient and your googlefu is strong you can find just about anything for that engine, except a bolt in EFI kit.
I planned on getting to the swap some more today, but I ended up spending all day (12 hours or so) getting the Cuda out back together so I can roll it out of the garage as needed. Maybe tomorrow.
