After engine reinstall, first start up ends in disaster!

Fired the engine up after a rebuild, started first try but soon happy turned to sad as a metal to metal tapping started. pulled the valve cover off and saw #7 intakes push rod was loose. Took manifold off and discovered my new Comp Cam roller lifter didn't look so hot..... and now they are saying it might be end of July before they have any more of these crappy pos's in stock. And since i have 7 other pairs already installed I guess I'm locked in to finding a pair....?

My machinist said he's completely avoiding comp lifters roller and flat tappet at all cost! Comp sucks.
