So I am getting ready to put my tunnel ram on my 460, my questions is the back two intake ports that are blanked off on the manifold which sealer should i use in conjunction with my gaskets? I did buy the felpro marine gaskets for it, i just want to make sure the seal is tight.
We use Permatex "The Right Stuff" for water ports and also in place of end seals, even if the gaskets are beaded.
I tend to do the same thing with alittle add-on! Toss the front and back rubber( going to slip out and make a mess) use straight black silicone. BUT I step up a pinch and dimple the block with a center punch just for a gripping effect. never had a intake leak at the front or back Since! Just be careful on how much you use, Silicone plays hell with an oil pump if it finds its way there! As normal good advice from the guys at Jbp!!!! Mark
