Sorry to bring this thread back from the dead, but I just had a conversation with Schneider cams and they DO make one hydraulic grind for the P90A head.
It is the mild grind good to 6000 rpm.
They supply the specific lash pad thickness to use on a by cam basis after grinding due to the smaller base circle since there is no way to ascertain the measurement with hydraulic setup.
Just wanted to make sure the proper info is available.
The nice thing about the cam is the 114 degree lobe centers.
