Should I rebuild a "good engine" to fix oil leak?

I've owned since new. My 71 with stock 318 was rebuilt in 1990 approx 70K miles ago. I ran compression check today and low was 146 psi and high was 152 psi. The engine is running great. The problem is that it drips enough oil that it is not welcome in the garage. (I have a new car cover still in box and gravel parking area in side yard where I can park it.) I'm preparing the car for a paint job and intend to keep it 'till I drop (hopefully 20+ years). I've not resorted to oil additives to stop the drip. I can easily replace valve cover gaskets - but the other minor leaks will require pulling the engine and probably involve a full engine rebuild after going that far.

I'm not looking for a show car - just want to keep my car looking and running good and I will eventually drive it as my second car rather than as my hobby car.

Debate is this: Should I rebuild it now or are there some reasonable steps I might take to reduce the drips for the short term and save the rebuilt for a time when engine performance tells me that I need a rebuild.

FYI - The car was originally Por-Red and, after over 20 years as a black car with agrey hood, it will soon be back to its original Por-Red with a black hood. The oil leak is more of an annoyance than a need.
