Well I was told from Tom at Stovebolt Engine Co that the best seal is a NOS type that has Asbestos in it. I took his advice and bought on from a Patrick J. Harris in Minden, NV. The rest of my seals and gaskets are from a kit by Best Gasket. I have not started the motor so I do not know how its going to hold but crossing my fingers. That's my 2 cents
