I am trying to get the head numbers from my brothers, I live 1 1/2 hours away. The intake valve is .040 into the head. We know it has to come back to flush. Will replacing the intake valves help/be necessary? How deep should the exhaust valves be into the head from the main surface of the head to the face of the valve? The head thatwas on the tractor is approximately .96". I should have casting numbers some time in the morning. My work number is 248-477-0040, home number is 517-546-2029.

Thank you for you help.
