I think the gasket could be bad and still yield a good compression result. With head gasket failure, you can have one of four situations:
1. continuity between combustion chamber and atmosphere
2. continuity between combustion chamber and coolant passageways
3. continuity between combustion chamber and oil passageways
4. continuity between coolant and oil passageways.
#1 and #3 give you low compression readings, #3 because the oil sump is in continuity with the atmosphere, anyway. #4 gives you coolant in your oil (foam). #2 gives you normal compression test because the coolant system is a closed system and the coolant, being a liquid, is non-compressible. I wonder what would happen if you drained the coolant and re-tested the compression.
