The car did overheat and cause the head damage, however, that appears to have been the extent. I have no idea of how old the engine is, but there was absolutely no ridge in the cylinders and the internals of the engine looked good so we just replaced the heads.

There is no backfire and the car idles as smooth as silk.

Temp seems to be reght at 190+/-

Thanks for the tip on the leak.. I'll put a vacuum gauge on the un-timed port and see what's happening there.

Additional suggestions would be appreciated.
