Markings on my cams

[Vee8ight]

I'm currently servicing my AJP, doing tappets etc, I've found some engraving on the cam between lob 7&8 and wondered if it meant something like lobe centreline or overlap? It says 106 degrees on both.

Thanks Darren

As far as I'm aware, it's, as you say inlet / exhaust valve overlap.
