Having no luck cutting out a replacement for my lost Gilbert .11 head gasket, does anyone have or know of a source for any of these gaskets?It's my understanding the heads are interchangeable so I assume the gaskets are also.Thanks.[/quoRegarding Fox 09/10 engines. I checked my stash of plugs and have about 10 Fox 09 plugs and 5 Fox 10 plugs. They are interchangeable with each other and the Gilbert 11.Now the downside. Duke was notoriously cheap with these plugs and there were no head gaskets included with them. You had to get a package of gaskets(3) to a package. I do have enough gaskets for the plugs I have, but no spares. I even have a NIB Fox 09, go figure. I'm sure it is in great demand to replace a Baby Bee 049 but it is an interesting collectable, I guess? Good luck with your search.Dennis
