Our record on this one is brief - just the description and the oversize spec, with no figure title or model breakdown to go on. If you're rebuilding a head and need a guide at this particular oversize, this is worth checking against your own measurements before ordering.
Call the shop if you want to confirm which engine or head this guide is meant for before you buy - we don't have that detail spelled out in our catalog notes.
