A valve guide is the fixed sleeve the valve stem rides in as it opens and closes, keeping the valve aligned in the head and controlling oil control around the stem. Guides get fitted in oversizes like this one when a head has been reamed out to clean up wear or correct a worn bore, so the .006 designation matters when you're matching it against what your head actually needs.
We don't have more detail on this one beyond what's in the catalog. If you're not sure which size guide your head takes, call the shop and we'll help sort it out before you order.
