Specs At A Glance

Good To Know

Q: Does this valve need to be lapped or adjusted after install? A: Yes, intake valves should be lapped to the seat and checked for clearance, then shimmed to spec during assembly.

Q: Should I replace all valves at once? A: If one intake valve failed, inspecting and replacing the full set is common practice to avoid repeat teardown.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
