RE: Gasket Materal
Loctite makes a gasket eliminator 515 sealant, part #51517. Fills gaps to .010 inches. Cures in 1 to 8 hours. I've used in in place of paper gaskets that are no longer available. It's also a strong adheasive, so don't go overboard with the application. I had a back plate that was almost impossibe to remove because of the excess sealant that got between the backplate and crankcase.
