These rockers any good?

I commented on your original thread. The reason I said what I did is because I hang around my buds machine shop. I have seen three wasted motors on account of these no name rockers. I think they are proform. Adjusters push thru or fulcrum breaks. Next thing you know lifters bailed its hole and pushrods takes its place. Ever seen what happens when a cam grabs a pushrod. It snafus the lifter boss and breaks piston skirts on the way down. Don't skimp on rockers. Daves66 has a photo thread on his
