Magnum Roller Lifters

my heads were gone over by a reputable guy...there again not mentioning names. absolutely no binding whatsoever. everything was checked and gone over before they key was even turned the first time. Same rockers were in the engine for the 3 years ive had it now. Rockers I was sold from him were I believe procomp or PRW? (Chinese rebranded)
my car is currently at my buddies shop an hour away from me so soon as I get down there ill get more pictures and ill get the actual brand of rockers. They broke across the casting line. its not a straight clean break as you can see from the pick but it starts at the front of the casting line and ends at the back of the casting line. With the way the world is now it seems like almost everything you buy is **** quality.
