I'm atamting to biuld a 944 turbo DOHC using the current 928 cylinder head I have. I need to biuld an intake manifold for it and would like to use the stock 928 flanges. I don't know if anyone has tried this. The 944 turbo exhaust manifolds bolt right up to the 928 head I have. So if any one has some for sale let me know. Check out my post on the 944 turbo forum.
