Common questions
What does +0.001 inch oversize mean for this valve guide?
The guide is 0.001 inch larger in bore diameter than a standard guide. It's used when the original cylinder head bore is worn and requires a slightly larger guide diameter to achieve a proper, tight fit.
Will this guide fit both 88 and 103 cubic inch Twin Cam engines?
Yes, this +0.001 oversize exhaust valve guide is compatible with both Twin Cam 88 and Twin Cam 103 engines from 2005-2011 model years.
Is this for exhaust or intake valves?
This specific part is for the exhaust valve position only. Intake valve guides have different specifications and require a separate part number.
