4.2L Intake & Exhaust valve guides

I know the ID of both the intake and exhaust valve guides are the same, as the valve stems are the same diameter. Anyone know if the OD on the intake and exhaust guides is the same?

Bill,
Moss motor web-site shows both to be same O.D. --- standard would be .502" dia.
First oversized = Valve Guide, + .002" (.504")
