Cam lift is 12.5mm, std type R valve springs bind @ 12.0mm.

Spec C's ofer a power gain over std cams from 1500rpm.
Idle quality is very good, - 900rpm.
Nb: Installation is critical, if installed by an amature, idle will be poor.
They really work well on std B16A's, Spec B's work better on std B18C's
Aftermarket ECU is required & good tuning.
Fuel pump, regulator & heavy dyty oil pump gear also recommended.
Reliability of product is not an issue.
