KMJ Performance Rockers???

I bought a set of the PRW's and the hit my comp and hughes retainers in the "arm pit" area.Tried shaft shims,didn't work.Then tried lash caps,didn't work.Then tried both,still didn't work.I know this isn't the proper way but just wanted to try something.Got extremely "P ed" off so threw them back in the draw.I guess I should of spent the extra money and bought another set of Hughes.But this is a "mild" 340 that isn't going to get used.Lesson.........if it's cheap($$) then it's cheap.
