GS750 head on a GS1100 motor?

[Homie]

I went out the to garage and measured the intake port inside diameter of a stock '82 1100 16V head that I had on the shelf and guess what - it is 32mm. Since you said you had to get an '83 valve cover gasket to fit your head I would say that you have an '82-'83 1100 16V head with the 24 bolt valve cover versus the '80-'81 heads which only have the 20 bolt valve covers. They put two extra bolts on either end of the cam chain tunnel to promote better sealing against oil leaks.

Homie. Thanks for the info on the Intake I.D. As for the jug numbers I've been looking on the wrong side. I'll have another look when I get home tomorrow night.

Found it. The number on the front of the jug says 1075cc. Is this right for a 1980?
