What would be the effect of worn.....

valve stem seals and guides on a compression test?
I am scheduling these repairs as soon as uncle Sam's return comes in. But I want to do a compression test on my own (25.00 in Sears for a compression tester). And before I go to the mechanic, I want to make sure about the condition of the engine.
Given the age and mileage (200K+ ?) of the vehicle what values should I look for? (assuming worn seals and/or guides)
It uses about 1 quart every 500 miles.
