Set of 10 ARP 1/2"-To-7/16" Head Bolt Bushings for 289/302 Engines.

Use AFR's head bolt bushings to fill the extra space created when using 351, AFR, or other aftermarket heads, which have 1/2" mounting holes, with a 289 or 302 block which uses a slightly smaller 7/16" head bolt size.

These handy washers are made to protect the top of holes from galling or collapsing around studs or bolts. Ideal for head bolt holes, these ARP head bolt bushings are CNC machined from premium thru-hardened 8740 stock.

Please Note: 10 Head Bolt Bushings are enough for 1 cylinder. 2 packs will be needed for both cylinders.
