The ring on the head gasket seals against the iron cylinder sleeve. as long as the sleeve is intact, and the sealing surface is smooth, the gasket should seal.

Well D day has come, just had a call from the shop and the boat is ready for collection. Question with out notice, the mechanis told me they cleaned the damaged area up and filled it with a product called ITW Devcon. Have any of you guys heard of this stuff? Awaiting a call back to tell me how much this little episode has cost me.

Devcon is best stuff on market, used in aircraft and such. I use it all the time,not cheap but the best.
