Perfect for your Mild or High performance Hot Rod. Note: We suggest using Proflow Head Bolt Stepped washers part number PFEAHF-HBW. Proflow head bolt insert washers are designed to be used on Ford Windsor cylinder heads in applications where you have 7/16" head bolts being used in 1/2" bolt holes. This stops the head bolt hole distorting on aluminium heads when using 7/16'' bolts on 289 / 302 standard Windsor blocks.
