Granted, a head gasket, fully blown, would cause (1)temp issues, and at the very least, (2)areation in the coolant, both of which should be readily detectable.

I'm not saying it IS a head gasket, just that it might also be a possibility since head gaskets have a greater incidence of failure in the LT5 than valves or piston/rings, under normal conditions. The other less frequent possibility is for a secondary butterfly shaft screw gets ingested.

You're not suggesting that copper is indestructible are you?
