The '02-'04 LS6 head has .6mm longer valves to account for the smaller base circle of the cam.

Anyone install the cam in a F-body or 2001 Z06? I'm putting my car back to stock and was planning on updating it to 2002-2004 405hp specs for resale.

I allready have the '02-'04 airbox lid and the OEM h-pipe w/ only 2 cats (2001s had 4 cats).

I guess I could re-use my 7.4" pushrods from my G5-X2 cam kit to give me a little extra pre-load to make up for the difference?

Any ideas, or is it a non-issue?

Thanks,
Brian

Search, this issue is one that no one can agree on. I pulled my 04 LS6 cam out yesterday that I ran with the stock pushrods for ~10k miles no problem if that helps. You are going to get different responces though. It is fine run em'

Thanks... nice to hear from someone with real experience. I take it you had no issues w/ pre-load or valvetrain noise then.

hello, i bought TSP (texas speed) ls6 heads & ls6 2002 cam (wimpy / low dyno #s) and it runs great using the stock pushrods & rockers. about 7k miles since install. i specifically asked and tsp said i didnt need to upgrade pushrods with my set up. the cam runs perfect, idles at 600 rpm. no lope and low dyno #s are the downside.

Did the heads come w/ valves? Were they the correct valves? If so, then of course you have no issues. The 2002-2004 LS6 heads have .6mm longer valves.
