Rob, Rick,
Thanks for the input. No complaints with the cam being different than the original LS6 [I think I can suffer with only 475 hp

]. I just wanted to be sure that such a different lash setting was correct.
I followed the EOIC method and have the driver side done. Most were in the .012-.013 range, though a few were more loose than that. The adjustment went well and pretty quick and I double checked them. The hardest part was getting the bump-switch connected to the starter when the engine is hot. Taking it back out now to warm it up again for the other side.
Thanks again,
Dennis
