I am attempting to mate an Edelbrock victor ram 7075 manifold on a 10.2 deck block with dart pro 1 325's. I have custom cut .065 Felpro gaskets glued to both sides of the spacers and also one on the manifold. The manifold still sits way low in the valley with nearly an 1/8 gap on the valley wall spacer. Is it common to continue to stack gaskets until the ports align? Are there thicker spacers out there? I dont believe the heads have a intake port raised from standard location and the manifold has not been milled.... Seems pretty hooky to stack so much stuff in there.
