I would think that on parts like retainers and springs they would have to maintain the uniform height for the engine to operate properly. On the cam gears, I'd say until it feels like it's on there tight enough. Obviously don't pull on it with two hands until it won't tighten anymore. It should just be until it feels like they're secure on there .spoonB18c1 said:1 Does anybody know if the skunk2 Titanium retainers are the same size as the stock GSR retianers?
2 Are the skunk2 valve springs the same height as the stock GSR's?
3 How much do you torque down the 6 bolts on the Skun2 cam gears?
