About This Product
This Colony head bolt washer set is designed specifically for side valve engines equipped with aluminum heads. These zinc-plated washers are essential for distributing the load of the head bolts evenly, preventing damage to the aluminum surfaces and ensuring a proper seal. This set fits 1940 to 1948 74 inch and 80 inch Flatheads, as well as 1940 to 1957 45 inch Flathead models. They are a direct replacement for OEM part number 16822-39. Sold as a set, these washers are manufactured to precise tolerances to meet the demands of vintage engine rebuilds. Using the correct hardware is critical when working with aluminum components to maintain the structural integrity of your top end.
