3020 diesel cylinder head interchange

HI!! The post from a few days ago about the 4020s head oil leaks got me thinking about a project I have coming up. Will the late 3020 diesel head (casting # R34860) with the pencil injectors interchange with the early head (casting # R32040)? The side console head even has a different casting number than the one I have above. Will it interchange with either of the numbers listed above? I know that injector lines and injectors would need to be changed but I have a while to gather up the parts before I start. The reason I ask is the JDparts.com parts books list two different widths for R34860 and R32040. My paper catalog says nothing about the width of either head.
Thanks
Ken
 
I do not know about a side console head but I put an early 3020 pencil injecter head on my 3010 years ago. For a 3010 I had to plug the engine oil cooler port in the head as a 3010 does not have one. We were overhauling the tractor and it seemed like a better way to go then spending the big money shops wanted to rebuild the big injecters. It has been 20 years since we did it and that tractor feeds cows every day. Tom
 
Pre-console heads will interchange regardless of injectors.
Console heads will not. They are too narrow.
