A motor that runs way too rich can cause oil burning b/c it washes the oil film off the cylinder walls. Can damage pistons and rings from lack of lube.

Could be that the oil rings were installed wrong, so thats why it's pumping oil but has good compression. Could also be overfilled with oil, too thin a weight, etc. Valve guides/seals a strong possibility. Puffs on startup, idle and deceleration are common with worn guides/seals. It's worth making sure the top end oil control is right. It's common to rebuild a motor and totally overlook oil control in the heads due to work guides, valve stems or incorrect seals. The result is a strong running smoker.

The first thing to check is what kind of oil control are being used on the heads. Come to think of it, the stock O-ring and deflector system sucks. A set of the blue vitons would be much better, if they'd fit the guides.
