Good To Know

Q: Does this guide work on both intake and exhaust valves? A: Yes, it is listed for both positions, so the same part number covers either location. Verify the required bore size for your cylinder head before installation.

Q: Is machining needed after installing a valve guide? A: Guides are typically pressed into the head and then reamed or honed to final clearance. Measuring stem-to-guide clearance afterward confirms the fit.

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