Re: Head nut/stud torque?

I just got a call today from a very frustrated mechanic in VA who is having the exact same problem on a 288 (same gasket and block as your 327). It makes me wonder if something very funky is going on with the gaskets. The VA head was freshly milled, and even with a low torque the gasket should hold water for crying out loud.

That said, I do always put my gaskets on with the old hot rodder's favorite of a heavy coat of aluminum paint on both sides.

I guess I'd try running the engine through a couple of heat cycles and carefully retorque to see if everything seals up. The last new gasket I retorqued a few weeks ago took an astonishing near half-turn on each nut after several heat cycles.
