Might be hard to find one for the aircooler but I'd try calling Cometic and see what they can do for you. http://www.cometic.com/contactus.aspx

If you search the boards I have found the 350 gasket fits but it has to be for the 329cc engine I believe it was and it does have the 7 studs. Or just buy 82300R's... I would if I had the money right now man!

Also you can do a search using my username and it should pop up a lot of 300R info. I did a pretty good write up during my build.

I just called Cometic about making me a .020in thick copper head gasket for my .010 over bore 85 Honda 250R and they quoted me about $28.00 shipped. Prety sweet for a custom head gasket if you ask me.

Cometic will make/do just about anything, and their gaskets are very high quality :)
