When did GM start using tick performance camshafts?

When did the tick stop on my GMC 5.3?
I bought the 05 GMC 5.3 with 130,000 in 2012. One year ago about 172,000 the tick started. until two weeks ago with 182,000 miles the Tick stopped but replaced with the CHIRP. So the tick stopped for now. A few YOU Tube vids on the chirp. So weird. A half bottle of SEAFOAM 6oz. added to eng ing oil.

What causes the lifter tick on a Vortec?
Another problem common amongst a lot of the vortec engine line is lifter tick. Lifters sit on the camshaft and are responsible for the opening and closing of the valves. The lifter pushes the pushrod into the rocker arms which is what then forces the valve open.
