IMS timing question

However, there`s a punchmark on the IMS sprocket, am I right that I can just ignore that?

If you know the answer or you have assembled a Boxster engine and paid/didn`t pay attention to this alignment I`d appreciate if you could chime in.

Thanks

The IMSB external flange is just a mount for the bearing to spin on. If it's a LN bearing just torque the bolts to spec & you are done. I would guess the punch mark is from the machining process.
