Thanks folks for the replys, but I am still a little befuddled, I know the port that goes accross the intake, under the carb can be blocked off with an intake gasket, What I am concered with is the big semi-circle holes arounf that port. in the head. looks like he** and a trap for dirt and small parts. Are those also covered by the aftermarket intake gasket?? To Chick: are you saying that instead of the stock type valley cover/ intakje gasket combo, that there is available a seperate valley cover and seperate intake gaskets? .
