Bigger valves in Farmall A,B or Bn

John-CT · Aug 12, 2010

Im looking to put bigger valves in my farmall bn that i pull with. I was wondering if anyone knew what valves i could use in the tractor or other things i could get the tractor some more horsepower other then boreing the motor and plainiing the head.

A good automotive machine shop will know what valves will work, but unless you are going to make some other, serious engine modifications, such as a substantial increase in rpms, those bigger valves won't make any difference.

As rusty says if all you do it the valves your not going to gain much if any thing. Plus for that type of $$ you would get more out of it by polishing things up. To get any real increase you would need to mill the head do something with the cam and also jet the carb and maybe even add an increased air input system sort of like a mini turbo
