Doing it yourself isn't that hard, but you have to make your own valve compression tool by modifying a stock tool. The moulded aluminum makes it hard to compress the valve springs to set the stays.

A valve job is a good idea as many of the 3e-e engines had valve oil seals that were factory defective.

Are you sure it's the valves? A busted ring could give a low reading as well. Before you spend the cash, squirt a little oil in each cylinder and run the test again. Better to be sure than have them rebuild the head and the problem was elsewhere.

You might also consider a leak-down tester. Screw it in like a comp gauge, add pressure, then listen at the throttle-body, exhaust, etc for escaping air. Doesn't give you numbers (actually it can) but a good idea of where things might be going bad.

agree w/azlar first check to see if the valves are the issue. elliminate the rings.
put a little hyper lube in the low hole. then redo your compession test. if the numbers raise significanly (they will raise a little), you know its a ring issue. also, check oil and water contamination, bad gasket. just to make sure.

both those dont cost $ to do.
