The lobes on the ZX11 cams are about 1/8" wider at the high lift point than the ZRX cams. If you have them side by side, it is easy to tell the difference.

Well if you have a good set of vernier calipers you can at least determine the height.

My ZX11 cams were:
Intake max lift 37.00mm
Intake base circle 30.25mm
for a lift of 6.75mm

Exhaust max lift 36.70mm
Exhaust base circle 30.20mm
for a lift of 6.50mm

For comparison my ZRX11 cams were:
Intake max lift 36.10mm
Intake base circle 30.00mm
for a lift of 6.10mm

Exhaust max lift 36.00mm
Exhaust base circle 30.00mm
for a lift of 6.00mm

Hope this helps.
