I show that P/N 964-105-247-07 is the left cam and 964-105-246-09 is the right cam for a 3.6L NA 964. Those are desirable cams because of their longer duration, not sure about the lift specs. Turbo cams normally have a 930 part number. However, any cam can be a regrind, so you have to be careful. Most camgrinders will stamp their numbers on the cam, though.

I don't know how the cam would effect smog emissions unless there was some lobe overlap that caused some unburned fuel to exit into the exhaust system especially at idle. You have a catalytic converter? The twin plug heads and ignition may slightly improve the burn but I have never seen a before and after smog check to know for sure.

It sounds like you have a nice engine there.
