Exhaust valve guide
Exhaust valve guide for the cylinder head, listed for the T140V, T140E, and TR7RV.
71-3295 is the exhaust valve guide used in the cylinder head on the T140V and T140E, and on the TR7RV, based on the catalog figures it turns up in. It's a straightforward wear item — the guide is what the exhaust valve stem rides in and seals against as the valve opens and closes thousands of times a minute, so it takes a beating from heat and friction on the exhaust side of the head.

You'll also see this part carry the suffix 71-3295E in the parts books, which is the same guide under a slightly different catalog listing rather than a different physical piece.
A worn exhaust guide is a common culprit behind blue smoke, oil fouling on the exhaust side, and valves that won't seat right no matter how much you adjust the tappets. If you're rebuilding a head from this era, it's worth checking guide wear along with the valve and seat before you button it back up.
