Cylinder Head Dowel Pins, 0.638 in. Outside Diameter, .503 in. Height, Chevy, Big Block, Pair

Why reuse your old dowel pins when you have machine work done on your block? I can't think of a good reason, especially when these Mr. Gasket dowel pins are inexpensive and readily available. They are made from high quality steel, precision machined and case hardened for accurate cylinder head alignment.
