Done wet and dry compression check 5 PSI on both. Removed head and checked valves for leaks, there were no leaks. No obvious signs of leakage on head gasket. No blow by with the engine running. What could be the issue?

If it were the rings, it should cause blow by right? There wasn't any, that was the first thing I checked before tearing down.
