Horsepower doesn't drop much with that much compression ratio. I've seen dead cylinders with more like 65 or 80psi.
If you care to do more reading on that topic I researched it trying to determine what is ok or not with airplane piston engines. They say it is more determined by how much oil you consume than the exact psi. The hp doesn't change so much with partially lower cr's.
Yes if the rings were very bad I'd expect more oil burn on the plugs, that is why I asked if you posted #7.
The air fuel and spark changes depending on engine load and rpm.
Valve guide problem I don't think so.
Valve seat sealing I would not think as likely because you mention increased oil consumption which typically would be valve guides or rings.
Relax and enjoy it.
