About This Product

MCS chrome rear tappet block for 1953 to 1984 Big Twins. Covers Panhead 1953 to 1965 and Shovelhead 1966 to 1984. Direct replacement for late 1976 to 1984 Shovelhead, except late 1982 models with specially routed oil lines. If fitting to 1953 to early 1976 cases you need a tappet screw conversion kit threaded for early-style cases and flat-style tappet screws to suit this late-style guide. Replaces OEM 18610-66B and 18602-80A. Sold individually.

Manufacturer part number: 502425.
