You could always do a cylinder leak down test. I prefer to do both a compression and leak down when diagnosing a problem. If it were a valve once you put pressure to the cylinder you would hear a hissing noise from the tail pipe if it were the exhaust valve or hissing through the carb for an intake valve. If rings were the issue the air pressure and noise would come out the dipstick tube or filler tube. I would have to agree with Ross. It sounds like a head gasket.
