Valve Guides are made of the highest quality manganese bronze material available. This provides additional clearance between retainer and seal for increased valve lift. Valve Guides provide excellent stability so they can be run with less clearance between the valve guide and the valve stem, thus preventing engine oil from entering the chamber. Combined with our Viton Valve Seals, you will have the finest valve guide and seal combination available. Sizing and reaming required after installation.
NOTE: These guides are .003" oversized (outside diameter) to fit into heads that have worn valve guide holes in the head. For stock outside diameter guides see part #1023078(ea) or #1023079(set).
