OEM Rocker Arm Side Play

These replacement Melling rockers measure about 1.652” and the originals off the 78 measure 1.662” Per pair thats .020” extra clearance using the Mellings, so the clearance with all the original 78 pieces would have been about .140” (vs. .160” w/Mellings) Still excessive. Ok? Apparently so. Like it? Nope
