Exhaust stud thread size - SF1

[Yogi]

Could anyone help me with the thread size of the exhaust stud on SF1?  Are all 750, 1000, 1200 the same by any chance?

Thanks,

Yogi

7 mm I think.
Triples ditto.

Pretty sure SF1-3 heads were the same. My SF2 exh studs are 8x1.25. Can?t remember triples.
Earlier SF heads had smaller, didn?t they?

So, would 8 x 1.25 be the same as M8, by any chance?  Just looking at some copper exhaust nuts..

Tippie is right: all 750s-"big heads" (36 carbs) have M8 studs.
All 750s-"small heads" (29/30 carbs) have M7 studs.
Found 7mm studs on 3Cs, don't know if they ever changed
it on triples.

Yep M8 by 1.25 pitch.

Brass nuts are readily available from the usual suspects.
Pick your favourite.

Thanks for that Grant.  I'll get some of those in that case...
