Intake manifold pulling oil
I put ultra grey down Intake flange and down the head, haven’t tried 2 gaskets stacked together but I ordered the .125” thick SCE gasket. I can try 2 gaskets stacked as well. Iv never had a problem getting it to seal up before I got valve job and porting done, using same head gasket I used before and nothing was done to either face of the head so nothing should be different
