I just had my timing belt tensioner break on me so I had to have the head rebuilt, I sent the head in with the cam's still bolted on. The machine shop sent the cams, bearing caps, and the spring caps back in a box. Does it matter which cam goes where (I think I figured out which one fits where best) and the spring caps can I just throw them on anywhere? Oh yeah I'm working on a 2004 chevy Aveo 1.6 dual overhead cam
