Bronze valve guide kit fits Big Block and Small Block Briggs Vanguard engines with OEM 6MM valves. The guides have been precision machined out of high quality bronze material; they feature a step at the top to prevent the guide from ever sliding down into the port or combustion chamber. This kit includes 4 bronze guides and 4 new valve seals.
Please Note: It is the builders responsibility to properly ream, hone and fit the valves to the new guides after install.
