Good To Know

Q: Does this guide work for both intake and exhaust valves? A: Yes, it is supplied for intake or exhaust valve positions in the 1503 cylinder head. Confirm the position and quantity needed before ordering.

Q: Why replace a worn valve guide? A: Worn guides let valve stems move off center, which harms sealing and oil control. Fitting a new guide restores proper stem alignment during a head service.

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