LT1 intake won't seal
So I've had heads milled .0010 of an inch, new valve guides, seals, valve job...... blah blah. All the necessary from having a blown head gasket. However, I didn't read that you should also have the head milled to match the heads?? Is this that important? I assembled everything and used the copper sealant in the front and rear of the intake, and the entire passenger side leaked. I sprayed parts cleaner along the entire intake to determine this. Driver side was fine. I only used felpro gaskets and copper sealant the first time. Then this evening, I purchased new intake gaskets(felpro) and some gray RTV silicone. It was very soft or runny in my opinion. I put a thin layer on the heads, and on the intake. Placed the intake gaskets in between( like a sandwich). And now it only leaks between cylinders 2 & 4. ? WTF????? I'm so pissed right now. What would you guys recommend I do. And I torqued the intake bolts according to Chilton specs, which I believe was 35ft/lbs.
