Mine is a fully roller engine, Nothing nasty, but its in the 570 lift. Im not really gonna do much of a break in really, but just nervous because its taken me 5 yrs of collecting parts, and getting enough cash to get it inn. Mine should be a nast piece, but I couldnt afford new rockers, so I got a good deal on a slightly used set off a buddy. Harland sharps, so I shouldnt have any issues.
