I may have mentioned it before, maybe not. Awhile back I got a package of gasket material from Ace Hardware. Part number ACE 4035499 It contains three sheets- each one is 6"x6" 1- 3/32" rubber (red) 1- 1/32" black fibre (their spelling) 1- 1/16" cork. I paid 3.29, plus Uncle Sugar's cut (tax). The black fibre is good for intakes. The other stuff is good for a lot of other projects too, like the gear cover or ??? Ace is the place for with your helpful hardware, man.
