S13 & S14 SR20 Cam Lobe Size Differences

I am trying to mic out a set of stock S13 Redtop SR20DET Cams but as we all know there is no English S13 SR FSM - SO I am wondering (if anyone actually knows)
Is there a difference in the cam lobe sizes from S13 to S14?

The S14 SR20DET Cam Specs are;
Intake & Exhaust: 37.920-38.110mm (1.4929-1.5004in)
Wear Limit: 0.20 mm (0.0079 in)

I would look at the S13 N/A SR FSMs but I would assume the cams would be different but who knows - that is why I am asking because I have no idea and cant seem to find the answer in my searchs.

Any help would be awsome!

According to my 180sx FSM, the specs are:

Intake: 38.103 - 38.293
Exhaust: 37.920 - 38.110

It doesn't mention a wear limit, so I'm assuming the JDM FSM would just have the cam replaced if it's outside of the given measurements.
