I don't know if the "X33" option is an SC or C2 cam profile, but I do know C2 or C4 is a 964.
Cam timing for 964 cams is 1.25mm

If you are tracking the car and want to move the powerband higher than time them later like around 1mm, and timing them earlier like 1.3 may or may not give a little more power at lower rpms.

I have Webcam cams in grind #40 which is a 964 or C2/C4 profile in my 930 and here is a scan of the timing specs that came with them.

I've heard the 930s or the '94 965 may have used these cams.
