    NO RTV.....if you had graphite gaskets you need to carefully remove all the residue. Do not use steel wire brush on the block or heads. Use a brass wire brush so that it will not scratch the aluminum surface of the block or heads.

    I agree - install them dry without any type of sealant. Stock gaskets are the way to go on our cars.

    I also agree with stock gaskets and new bolts. I got the GM replacements fairly cheap. When you get them on and torqued to spec start it and let it heat up then give each bolt another pound. Will help bolts from coming loose. Just don't burn your hands!
