Geoff - To your original comment/question regarding less contact mileage between the lifter and lobe on a re-grind/smaller base being potentially better - I don't know.
But for a given lobe profile/lobe area, the smaller the base circle, the harder the lobe whacks the lifter. The contact patch effectively moves further out on the lifter surface, kinda like a faster rate lobe would, but its not a faster rate lobe. I think this would be less beneficial.
