The Exhaust Valve Guide suits a shaft diameter of 3/8" (9.53mm), the guide has an outside diameter of 17/32" (13.49mm). The guide is 2.0625" long

When an exhaust valve with a 5/16" stem is to be fitted a special guide is required with an internal diameter of 5/16" and an outside diameter of 17/32". Order set RTR1049.

Note that valve guides are supplied with the I/D approximately 0.003" undersize so that once fitted they are honed out to be a perfect fit to the valve stem. Likewise the O/D is 0.003" oversize to ensure an interference fit in the cylinder head

For reference a TR4A head has guides to suit 5/16" valves with an outside diameter of 0.5025" (12.76mm) in all 8 locations.
