I would suggest that your engine is badly in need of a rebore. It is very badly coked up, due to burnt oil collecting in the combustion chambers. With the current pistons at 0.040" there is scope for a re-bore, fitting a set of 0.060" pistons and rings, which are available at our cherished suppliers. I would invest in a complete overhaul of the block while you're at it, valves, seats, guides, studs, surfaces. It will be worth it in the long run. Throw the oil baffles away (if they're still there) and fit a silicone base gasket.
