Randy,..that was the basis of my suggestions,...
Assuming for the moment that the valves, guides, and guide seals (Viton, I hope) are all in perfect shape doing their collective jobs, its time for Brother David to pull the cylinders and start checking the ring clearances, surfaces, bore dimensions and concentricities.
I've had perfectly good pistons with new rings in otherwise OK-looking bores just smoke like the dickens and the cure was always new P/C's.
Oftentimes, the bores are no longer round and new rings don't really seat well under such circumstances, even after extensive de-glazing.
