I did use spell check...Spell check for rednecks......lol The instructions Called for 3 gaskits to be stacked on top of eachother...Holley tech said they wear wrong and only to use one....  Red means gaskits i wasn't to use....Blue means the one and only i was supposed to use

Yeah.. double gaskets aren't entirely the best thing to do. Just use the blue one and be sure to caddy corner when tightening. Other than that, just make sure the surface is nice a clean and theres no gunk or anything that could interfere with the gasket sealing.

Other than that I don't really know what else to say, if I was there I could more than likely fix it. I'm good with Holleys.

Have you checked the surfaces to make sure nothing is warped?
