2009-10-Z Head bolt washer set

Proper hardware is essential for the longevity of a vintage flathead, and this Colony head bolt washer set is a perfect example. These washers are designed for 1929 to 1973 45-inch side-valve models equipped with cast iron cylinder heads. Finished in zinc, they are a faithful reproduction of OEM number 6486. Using the correct washers ensures that your head bolts seat properly and apply even pressure across the cast iron heads, which is vital for maintaining a good seal on these classic engines. Sold as a pack of ten, this set is a must-have for any mechanic working on WLA, WLC, or Servi-Car models that still run the original-style iron top end.
