Your other option is to go to the hardware store and look in their siding, flashing department and see if they have some copper on a roll. then just trace the one you have and cut it out.

Is it my only option? I just think it will be hard to cut that piece of copper, what about sealing the block with a high temperature seleant?

 

[Datboi]

Even the best high tempature sealants cannot withstand temperature that occur around the combustion chamber and exhaust manifold.

HVAC or also know as Aluminum tape can work in a pinch. Did this on the side of the road a couple times before and flabbergasted one guy watching from a coffee shop thinking it would never work. Would stick a square cut out from a roll and carefully place it on the cylinder avoiding wrinkles. Then I would cut out the stud holes and around the bore with a 48mm circle precut out as a template. Then would continue building layers, get a good 6-8 of them and then reinstall the head normally. Works for a good 50 miles at a time if your already running right. Any other airleaks or lean temps would quickly cause it to break.

Now I just ride with extra parts and have plenty on hand.

My ducati monster has seleant around its cylinder ....

Your gonna order a new head so order some copper head gaskets. The epoxy you used on your cracked head ain't gonna work anyways

Never use gasket maker for a head gasket

Oh. I'm not planning to use a gasket maker, I'm gonna use the alluminium one and put seleant around it like on my monster
