Valve seals look okay. Im thinking the issue might be unseated rings from glazed cylinder walls. I can see a yellow looking film in portions of the cylinder walls. I bought some seafoam top engine cleaner and will try that. Would it be foolish to think about trying the Bon-ami treatment? If that doesnt work ill have to take it apart and deglaze them.

Assembled the pistons in the bores with motor oil? High speed glazing is why I used MMO or ATF when assembling an engine. Try adding MMO to the oil then running the engine fairly hard. MMO burns off the cylinder walls long before it can cause glazing.
