Have seen alot of arguments about what will fit. Well, bought the Hughes retainers and spring kit along with the comp cam show in picture. When we checked clearances, the retainer HITS the valve seal at .530 lift. Obviously won't work. Thought I'd save some headches. Have a video on facebook.
Because of the lifter angle on the sb mopar...you lose some lift, maybe not enough to fall into the accepted tolerance, but I can tell you right now...you won't see .536 at the valve with a 1.5 rocker.
