OK what the differencein the heads, to the running of the tractor?
 
Cooler, ported different?
 
 
Why the taller WD45's heads ?
 
Gaskets, Valve Size, Guides, and the Push Rods are the same? right?
 
Thanks !!  Teddy    
Ac D-19, a Number of WD's, One WD45, Two 444 balers, Ac plows and etc.

The 45 head has more cooling and the 45 head gets the spark plug closer to the center of the combustion chamber.  Other than that, I'm not real sure.

Teddy, that's a good question.....I been told not much difference, performance wise
I am still confident of this;
I will see the goodness of the Lord in the land of the living.
Wait for the Lord;
be strong and take heart and wait for the Lord. Ps 27

The Tall head, introduced on the WD in mid 51 and carried over to the WD45, moved the plug toward the center of the combustion chamber and eliminated the little pocket the plugs sat up in before.  It unshrouded the plug for less fouling and increased compression just a little.
Most problems can be solved with the proper application of high explosives.
