How much wear on the rocker-arm-to-rocker-shaft surface is acceptable? My 440 measures (with a caliper) about 31/32" ID on the horizontal and about 1" on the vertical surfaces. The oiling groove looks about 1/32" deep. Will new lifters take up this slack? I would appreciate hearing recommendations & experiences.................James ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
