"When using a touring cam the lifter base diameter should be larger than a standard A cam requires. Many lifter bases are about 1.00" Some are 1.12" and these large base diameter lifters are necessary for the higher lift cams."

Wrong and wrong!!!!
I don't know what lifter diameter Bill Stipe designed his cams to run on but I would venture to say that most all of the regrinds done by other people were designed to run on a 1 inch lifter. We run cams in model A's with .415 lift on 1 inch lifters.
If a cam is designed to run on a 1 inch lifter it will NOT catch on the edge of the lifter. A larger diameter lifter face will work but is definitely not required.
