Not sure about weighting and heat treating aluminum - it sounds like the
source of more problems to me. Several years ago I had a severly warped
aluminum manifold on a small V-8. One clever mechanic recommended epoxy
under a new gasket instead of big $ for a new manifold. I went with his
idea. He kept the car over 24 hours for a "good cure" of the epoxy (I think
he used JB Weld). Success! I drove the car several thousands of miles
afterwards and nary a leak

Can an overheated aluminum engine head be heat treated (with weights on
it to keep it flat) to bring back its temper and hardness?
