I would start with monitoring how much oil you are really using and over how many miles. What kind of valve covers do you have, real GM covers with baffles or after market without baffles or cheapo baffles? If your collecting oil in the PCV hose you either don't have baffles, have very cheap baffles, or blow by. Did you bore then hone or just hone old bores? To what spec? With your engine up to operating temp pop off the oil fill cap or the PCV and see if you have vapors coming out. Work on getting the external leaks fixed and see if that makes any difference in your consumption rate.
