Here is one simple test I use. Not sure how you are set up on crankcase venting. Plug the PCV . I make sure everything is sealed except for one point. Run the engine until hot. At the one crankcase venting point see if you have positive pressure. It should haze out. If there is no haze or possible slight vacuum the intake is leaking.
Performed this trick today . It builds pressure pretty quick. . SO Im fairly confident the intake is sealed up fine
New spark plug tubes will be here in a few days..
Regardless of what changes they make ,,,If any.
I will live with the results till maybe next year And as the piggy bank rebuilds I'll decided how deep to go into the engine in regards to just piston rings, possibility still may be a complete piston change or just have heads done
