Thanks. I was wondering why NAPA listed 2 part numbers. I'll go with the -190 thicker one.

There'a a guy...most good stories start that way...in Tennessee that makes Cessna/Piper silicone gaskets. Says he can make a Stovebolt cover gasket. I'll try one and report back.

Thick gasket, Permatex on head, not cover. Thanks for the help.
