About This Product
This Athena tappet block gasket is designed for a wide range of vintage side-valve engines, fitting 1930–1973 45" Flatheads as well as 1937–1948 74" and 80" Big Twin Flathead models, excluding the K and KH series. It provides a secure seal for both the front and rear tappet blocks, preventing oil from seeping out of the lifter area. Built to match the original specifications, it serves as a high-quality replacement for OEM 18631-30. For the mechanic servicing these classic machines, this gasket ensures that the valve train remains sealed and the exterior of the crankcase stays clean during operation.
Manufacturer part number: S410195015027.
