Are the GQ TD42 and the GU TD42T heads different?

I was told they are different but I couldn't see why.

Not to my knowledge, their may be some casting changes through the years as is normally the case as manufacturers chase emissions and weight reductions. They yeild the same compression, comp chambers, valves, manifolds and so on are all the same as far as I am aware. Their is certainly no performance difference between them.

I think the pre combustion chambers might have a larger opening on the TD42T head. Garth or Smash250 who ever it was with the recent build up 200rwkw TD42 thread had pics of it I am fairly sure.
