You need to clean the **** out of the head and block decks. I used a green scratch pad to get every little piece of anything off the surfaces.
You can also give the gaskets 2 light coats of permatex copper spray to ensure a perfect seal. But the key is to have a extremely clean deck surface.

used my dremel with wire brush on it, ver fine wire brush! Sprayed Engine Degreaser on it first, then dremel. Shaved a bolt down on opposite sides so i could thread it in and pull crap outta bolt holes.Highly recommend this step to get crap out, also paper towel rolls in those holes to get all coolant. Hydro-Locking Head Bolts really, really, really Sucks!!!
