Make sure that both the head and block surfaces are dead flat. Type of gasket unsure though, ACL used to be the go but they are no longer made

Janspeed thought fuse wire could sort the issue, never really heard of this working first hand.

I used a 1275 gasket on a 68mm bore 998 with a 12G202 head, but a few water holes had to be moved in head and block.

Thanks for the advice. Might explore the 1275 option further. I've heard that they will fit with some modification to align water jacket
