Paul's motor doesn't have any of these problems

AL.

Please explain why the LT5 head gasket failure would necessarily affect the adjacent cylinder. Each cylinder has an individual copper seal. LT5's are prone to head gasket failure at about 7:00 position, into the coolant area.

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.
