I'm in the middle of building up my engine a bit. New cam and heads. My only questuion right now, but Im sure I will have more is, should I be putting gasket sealer like Indian Head Gasket Shellac on my head gaskets also? I've heard mixed reviews, I was told not to because it'll make the gasket imperfect and cause the head gasket to blow. But then I also heard it will keep it nice and sealed. Any information is great. Thanks in advance!
