Which sealant should I use? I was thinking of using Permatex 27039. It is good up to 750 degrees and has a 2 hour working time. It does say "Note: Not recommended for head gaskets or parts in contact with gasoline." Probably minimal contact with gasoline on the intake side.permatex.com/products/gasketing/red-gask ... red-rtv-silicone-gasket-maker-3-oz/
