So after getting my power brakes installed on my coupe I go out to the garage to continue to break in the pads and I turn my car over and am greeted with this obnoxious noise! I am pretty sure that it is a lifter or a push rod not sure which. Any insightful ears are appreciated.

Yep thats a safe bet.

I had the same issue I used one of the mechanic stethoscopes to locate the source of the clicking. It worked very well I simply placed the probe against the valve cover and moved along the lenght of the cover until I could hear the clicking through the stethoscope. Pulled the cover off and found a rocker arm flopping around and a bent pushrod.

I would not drive it until you can id and repair the issue. I let mine go too long and it damaged the valve stem.
