I have a newly acquired 1951 Allis Chalmers wd that I was recently informed has a stuck valve over the number three piston. My question is that when I pull the head off to get it rebuilt, can I have it redone to where I no longer need to run leaded gas. Or can I have it rebuilt to run normal unleaded gasoline?

All these old tractor run on low compression and the unleaded gas will not hurt them. It is a myth that you need lead in the gas to keep from burning valves etc. As for your valve problem I have run into stuck valves many times and have yet to pull a head just for that problem. If it is an exhaust valve that is stuck pour some ATF in the exhaust pipe and also fill that cylinder with ATF and let it sit for a few days. Then with the valve cover off take and try to turn that valve and also hammer it down a tad and turn and pull up on it. Do that a lot of times will free one up and then your good to go. Just had that problem on a 14HP Koler and the ATF fixed the problem in about 4 days

All you need is a set of hardened valve seats. I'm not sure most of them are run hard enough to worry anyway.

you need hardened exhaust seats if you run unleaded gas . it doesnt keep from burning a valve but the lead does keep the seat from being beaten up into the head. I gaurantee your seats when checked are to far up into the head. This can be remedy two ways . One replace the seat . Two cut existing seat to a larger valve size.
