I received my new manifold and all my gaskets. I was hoping to get my seloc today but its not coming till next week. My question is when I removed riser there were three gaskets on the manifold port. ONE metal directly on manifold. next was a
green gasket. Then the restrictor plate then another green one and finally the riser. Is there any reason that they would have done this. Manifold came with new graphite one
but I ordered two vp gaskets just to be safe. should I just eliminate the double gasket
