Rings for KB pistons 4.080

If the cyl were honed properly for the type of rings you have...?..... then i would be looking elsewhere for your oil consumption!

Like the intake gasket......if it didn't seal on the underside, it could be sucking up oil from the valley of the eng.
Have you pulled the plugs and compared then to each other? are they all oily? just one or two..............that should get you started down the Right Path.
