EQ headed LA

Hey guys awhile back I bought a set of EQ heads and threw them on my 77 LA 318. Over the past month ive been having problems. First off one of my rocker studs wiggled loose and i dropped a rocker and blew the lifter out of the bore. At first I thought it was a bad lifter (summit brand) but end up it just being the rocker stud. For piece of mind since it was apart I put a brand new set of Howards lifters in (hyd. Flat tap). This past weekend I got a popping sound comming from the engine....
