1992 GMC Vandura 2500
Question: over tighting

If you over tighten the rocker arms (connected to push rods) the engine will not have compression so it won't fire, You possibly could have bent some valves, Did you back off on the rocker arms?

well one of the push rods broke and one bent but the motor never started

OK you need to check the other push rods by rolling then on a flat surface to make sure they aren't slightly bent, Then go purchase the amount needed and make sure you bring a sample so you can get the proper length and diameter.
