I know who built it in his garage and know it turned out to be a hassle for him, both when he was lending it out and after he had sold it to whoever has it now. That's why I said in my post that it was no longer available.

BUT, it was built in a garage by someone who was not a metal fabricator, just smart. And whoever wanted to build one could do it with a hacksaw, a welder, and a few other tools to measure and clamp. Start with a bare LA cylinder head and work out from there.
