This is what I'm going to do to my S/F heads, open up the head for a 4" cylinder, use a custom made adapter ring that Il make from 5mm alu or steel? It will adapt the big cylinder to small head. The head will be step cut to make the adapter flush fit i the head.
Yep, Dustin was thinking of going that route, but he know a really kick but welder, and we are trying that way on the frankenstein 044s, do you have pics? Definately post 'em here when you get them. I will do the same.
