I have a extra bottom gasket I keep just for marking the bolt pattern. Again punched the holes small with a drill then with a pointed grinding bit relieved them out to the right size. Coat of spray copper head gasket sealer on both sides and good to go. Oh while the head was off I lapped it in again on a piece of glass. This is the second time. It was heat warped again. Took about 3 minutes to get it flat. I'll be buying a billet head from Pirate Cycles as soon as Jim resupply's them.
How do you do this lapping on a piece of glass thing?
