Good To Know

Q: Do I need to replace all the valve guides at once? A: Replacing them as a full set is common practice during a head rebuild so wear stays even across all valves.

Q: Does the 420254882 number mean this is an original part? A: That number is an OEM cross-reference for fitment purposes only, and this item is not an original brand product.

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