M116/117 cam lobe dimension

Would someone use a micrometer/caliper and measure a known, good camshaft lobes from the base circle to the tip of the eccentric of the lobe? This is on #08 (intake) and #09 (exhaust) cams.

I have a cam which mic's out at 1.63" on the highest/thickest lobe down to 1.62" on the lowest intake lobe.

Exhaust lobes ranged from 1.645" to 1.62".

I realize some of the difference can be attributed to operator error as, while mounted in the car, the lobes can be quite tricky to get a "straight" shot in order to get a good measurement.

Lobes show no sign of scouring.
