Cam swap without pulling motor

If you have a John Deere dealership close go get some caps for a 4440 tractor. 3/8 stem can buy 1 or 2 to try, they use to be like 2 bucks each.

Do they sell them in 11/32?

Any oem head I do gets 11/32s. Seems crazy to use 3/8 valves today unless you already have them
