MS4 Cam LS6 heads trouble??? (start up video added) finished installing h/c and I started it and it idled great, but the third start after a couple of adjustments (tightening header bolts, adjusting coolant and oil levels) the car would continually die. I was wondering if it is just the tune, since the cam is slightly larger??

Do not do that before you tune, do that as a last resort. If it is just a matter of driving to the tuner, just open the TB blade screw a bit to get you going. Do not go WOT. Just part throttle to the tuner.

Surely its just that its not tuned, you are probably over worrying that something is wrong, start it from a cold start and let it idle till it gets to operating temperature, that will help it learn the new idle and help it till you get the tune.

stock Ls6, Ported throttle body. I'm about to get a 92/92 Fast, Pro Charger, and a SixSpeedsInc. STG 3 + Transmission upgrade. Last weekend i raced a 10.98 03 cobra that my friends seen run at pinks STL with a automatic manual valve body on the street from a 40 roll in 3rd gear and we were door to door. He would prolly murder me from a dig lol he hooks like glue but he ***** when my LSWNDR pulls next to him on at about 65 lol.
