The biggest most noticeable part of the post was that he is using 1 quart of oil every 500 miles! That is some hefty oil loss and is most likely burning it due to the smoke he sees. Most likely a head gasket, but I was being nice and saying other things as well. Valve stem seals and rings even when worn pretty good will not allow a full quart in most cases to be burned in 500 miles. At higher RPM the head gasket will tend to leak more if it is going south. He should check his oil and coolant for any oil or coolant where it should not be. With that kind of loss it is either leaking out of the engine and down the block or into the combustion chamber. Either way something is seriously leaking. And the M103 motor is known to have head gasket issues after a certain amount of miles and time.
