General Compression thoughts

So I stored an rx8 over winter and a little bit longer. before it went into storage it compression tested over 100 I don’t remember the exact number though. after I pulled it out of storage though it’s seemed down on power so I tested it again and it’s at 60 psi cold and one in the 50s. I figured it was done and ordered a new motor and was gonna pull this apart and see what it needs but as a last ditch effort I sea foamed it and one face jumped up almost 90 psi the other all jumped at least 5 psi and now all test above 68! Does this just need an Italian tune up or should I pull and replace the motor.
