Gasketing I use Permatex's " The Right Stuff " in the Foo-Foo can , it also comes in a tube . I glue the gasket to the rockerbox , this way you can remove it easily and not worry about improper alignment nor nicking the gasket on the head when you're working . It'll usaually try to creep as it dries so I like to glue it them lay the rockerbox on a hard flat surface & weight it there to peven the gasket from creeping . Remember : wipe the edge with alcohol or starting fluid to de grease it before laying on that tiny bead of glue / sealant / RTV .
