ok. so what are fastners? And where would these locating pins be located if they were there? are they on the heads or are they on the intake? if they are there of course. And i am going to ditch the studs for sure. I am 90 percent sure that i have a vaccum leak at the intake, brcause like i said, its doing the exact same thing it was doing the last time i had a vaccum leak at the intake manifold gasket.
Also on this fel-pro gasket, does it matter wich was the gasket is installed? It's blue and grey on one side and then just grey on the other side, and on the side with blue and grey there are etches etched into the gasket material outline the ports of the intake.
