Sup fellas, just put some PRC 2.5 5.3 heads on my LS1 that had already had a cam/tune done. Think it's safe for me to drive about 30 miles or so to get it tuned? Wanted to stab on it a couple of times as well to make sure everything is working fine.

You will be fine. I might hold off on stabs Incase you find it a bit lean at high load due to flowing more air with your new heads

If you have the same old injectors on it, you should be fine for cruising and part throttle.
