I gave two blocks here that I think are GS1100 4 valve. One says 1074cc the other says 1075cc. They look the same. The 1074 has the marks of a rectangular head gasket on it, the other nothing.

They can both be 16 valve Jay.

Jay, the 1075 marked one , i think is a gs1100 2v block. nick

I've seen 1075 on a 1980 1100E (16V) block and my '82 1100EZ said 1074 on the block. So both of them could be 16v blocks, as far as the markings are concerned.

in the USA i have removed both from 1100 16 valve models.

We have a 1100 2v block on the way in for pistons. I will have the chance to compare.

Yep, my 80' 1100e 16v is 1075.
