Timer lobe mark

I am finally getting to check the timing on my panhead motor and noticed that the timer lobe mark is a little off the highest part of the cam lobe ? Is the that correct?

The mark on the lobe is a reference point for approximate timing. Timing is NOT set on the high point. Points are gapped on the high point, timing is set when the points are just beginning to break on the front cylinder.

That mark on the breaker cam can be used when running your valves. When that line comes jut past contact with the points breaker and the points are just starting to open up then you may adjust both of your front lifters. And the then you gently bump it around to the wide lobe and there too when the points just begin to open you can do the rear valves too. It's all so easy once you figure it out, no? RooDog
