There isn't a "flat spot" where the bubble size is static because of the volume difference between the cylinder and the bubble.
You've convinced me - Thank You, I will try that shortlyReminds me of the doubters who are not convinced that the acoustic method of setting cam belt tension (on my other car) is sheer genius.

I have added a pointer/edge so that I can use a mark on the a/c pulley

Told you! Glad it helped.

Now it's really clear that the cam timing is totally FUBARed, which explains why it maxes out just under 170mph.
There's not enough adjustment within the sprocket slot allowance, so now I have to find a way to shift the cam chain one tooth at a time, with the timing cover in place and the engine in situ.
This is really going to be horribly difficult, or physically impossible.
I am not looking forward to find out which.

Shouldn't be too hard to machine the slots on the sprockets surely?Now it's really clear that the cam timing is totally FUBARed, which explains why it maxes out just under 170mph.

No need for anything so dramatic! First, get the cam where you want it and then 'walk' the sprocket around to a different position keeping the chain and the rest of the engine exactly where it is. you'll find that when you've moved it about 90 degrees, the slots will line up, aim to start with them roughly in the centre of the slots so that you have scope to go both ways.
