Good To Know

Q: How many valve guides does one order include? A: This listing is for the valve guide as described, so check the quantity you need against your cylinder head before ordering.

Q: Do I need to machine the head when installing new valve guides? A: Valve guides are typically pressed in and reamed to size by a machine shop, so professional installation is recommended for correct valve stem clearance.

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