Valve guide for the BSA A10 engine, .002 oversize.

The .002 oversize spec means this guide is meant for a bore or bushing situation where the standard size guide won't seat right, typically when a head has been reworked and needs a slightly larger guide to true up the fit. If you're not sure whether your head needs standard or oversize, it's worth checking your specs before ordering.
We don't have a lot of additional detail on file for this one beyond what's in the description. Give us a call if you want to confirm it's the right guide for your particular A10 before you buy.
