If your concerned about lobe width, you could send your old, OE 068 to Bulllet/Ultradyne and they can regrind/dress/polish it for you. Less expensive than a new cam and you get a nice new surface to break in a new set of lifters. That's an option. I too have noticed the lobes being more narrow the last 20-25 years on many cams. Can't say if that's a problem or not, but millions of cams have been made that way.
