How do I close both valves is it by manually turning the engine, and how will I know when both valves are closed, Iv never done this before so I dont want to screw up my engine. Also "MAKE SURE THE PUSHRODS GO BACK IN THE SAME SPOT THEY CAME OUT!!" is there a wrong way to put them back in, a certain direction they go or do you just mean put them back in the same hole they came out of? Thanx for the help and sorry about all the questions
