Exactly what Doug said. With the plugs in, there is no where for the air to escape the cylinders. Therfore, it must be compressed. No plugs allow the air to escape, and you to be able to turn the motor over by hand.

Congrats..you have cylinder pressure.This is a good thing.Fire the sucker up and after break in...measure the pressure with a gage for future referance.An across the board cyl pressure test is a valuable diagnostic stat if you experiance a weak cyl down the road.:hurray:
