Hi James. As far as testing compression goes; it is typically better to test Compression, cold, when you are trying to diagnose a performance issue. Testing compression @ running temperature is fine, but expansion from heat can sometimes disguise a problem.
Make sure that you are adjusting your pushrods, cold. Also, you need to be confident that your Andrews cams were installed/timed correctly.
You may have a failing ignition, or coil.
Check your charging system and check for an intake leak.
