The Z06 cam has a smaller base circle than the LS1 cam. The Z06 uses different size pushrods and beleive the height of the valves are different to compensate for the difference. Technically if swapping a Z06 cam into a LS1 or other LS based motor the Pushrods length needs to be checked to determine what size is needed. The stock length for a LS1 is 7.400 but some recomend getting a 7.425 length. I found all this info out because I wanted to swap a Z06 cam into my truck. Ive read on LS1tech or some other forum of people talking about valve train noise after the swap. I belive all they did is swap the cam. Ive also read that some people had no noise after the swap. If youve got the noise I would try looking into getting the longer lenght pushrods.
