Does anyone know if the steering head angle was changed between the 400 and the 426?

I know somewhere along the 400 line they made the rod bigger ('99 I think) and I believe the 426 has a larger wrist pin. Steering geometry changed in '00 or '01. The carb is a little more refined with more stuff integrated into it rather than hanging off of it. Suspension on the 426 is better (valving not as harsh).
