I just noticed you have pacesetters. Probably not the same torque specs

Probably nothing to be concerned about if it is a little lifter noise...most LS1's make noises.

It could be a header leak, a lifter, a rocker arm, or a bent pushrod. Maybe you over revved it and a valve touched a piston.
I would pull each rocker off one at a time, check the pushrod for flatness on something flat, like a mirror, and inspect the rocker. Also check the pushrod ends. Then put it back together and check lifter preload. Try to put the pushrod back in the way it came out, with the same rocker because they had been worn together.

post a soundclip/video

if it sounds like a sewing machine its just an ls1 being and ls1, if its a single clicking it might be a bad lifter, maybe even a spun bearing, but we need a video

yea it could be a ton of things. without actually seeing the car or hearing the noise on a video or sound clip then were all just shooting in the dark here.
