The Kaase lobe seems to be a little more aggressive than most of the lobes I could find in the Comp lobe family book. Maybe Kaase is taking advantage of the larger cam journal size that the big Fords have?
You're probably right, the variation and listed values probably differ because of various lifter wheel diameters. The HXL lobes have a good reputation with a few people I know.
