really not as much of an issue with modern LS stuff. Older engines with flat tappet cams required a 30-45 minute 2500 rpm run in when first fired to break-in the cam. The higher exhaust temps with the car sitting still (no real airflow) will dull the header coating in most cases.
New LS stuff or roller cam engines don't need that break-in, so if the tune is okay there's no heat issues.
