Engine Modifications
- the injector tips are Washington-style on the outside and Atlas-Imperial-style on the inside
- the fuel pressure regulator has an Atlas-Imperial seat and stem -- inferior to the reversible Washington design
- the new valves are one-piece
- the valve cages have new noses and are not one piece
- the guides are off the shelf (likely from MAN)
- the rod bearing nuts are nylock and not "large profile"
- the clutch guide pins are two piece
