Yep. I'm using an 1100 exhaust manifold gasket on my GP1200. The cooling jacket passages are opened up quite a bit more on that gasket then the 65u gasket.
Here's a pic of the 65u gasket:
You can see the 1st and 2nd water passages are restricted quite a bit compared to the 3rd hole. On the 1100 gasket, the water jacket opening on all three looks like the 3rd one on the 65u gasket.

well my memory was close to be right. I found a pic here that shows the difference.

Can someone tell me which way to install the "restricted" gasket on my 65U GP1200? the gasket can be flipped and go on two ways, I'm not sure which cylinder gets the open less restricted ports on the gasket.

Looks like there's an "F" in the gasket. I assume that would be towards the front?
