With out looking it up , Deere made changes to the cylinder head & improved
the air flow into the cylinder, giving it a swirling affect & it increased
the horse power without changing the bore & stroke. The think the piston face
was shaped different also.

Its the design of the heads and piston to give better turbulence in the motor for more power

The head was redesigned in '47, as below, to give better "swirl" as the air fuel mixture was pulled in. The heads will fit the pre '47 tractors.

Take a look at the information below from a circa 1947-48 brochure.

Hope this helps.
