Also how do I know which valves are the intake and which ones are the exhaust because I forgot to label them in the order I took them out. Someone please help!

Not sure when you posted this, but if you still need to know, #1 cylinder is the first piston on the back row (closest to the alternator). Its 1, 3, 5 across the back and 2, 4, 6 up front.
