Your machinest is full of S....T.
That is a lot of miles. But those engines are not hard on rings or valve train parts. Aside from pressure testing and milling the heads, HAS TO BE DONE.. A valve job/seal replace will help excessive oil usage. As long as coolant is kept out of the oiling system. I've seen the short blocks on these go many many miles. It's the intake/head gasket problems that kill these engines. Or in this area of the country the trans goes or the engine cradle rots out.
