What are the exhaust port dimensions and the bolt pattern on a cylinder head of a 75TS? I'm planning on manufacturing a turbo exhaust manifold for my car, but unfortunately I don't have the cylinder head available right now so that I could measure it... I'd appreciate if someone could do that for me it. Thanks!

My 75TS is on an engine stand. I just went out and meadured the ID of
the exhaust port exit is 34mm. The distance from center of the stud
to center of the stud is 68mm.
