I do this with every cam change. Chased a lot of noise from cam swaps before. I have never had a issue since I started using stock gear. I used to install a lot of cams in evos.

I have swap gear. Run engine and wtf, still hear the same tic-tic-tic noise 
I measured gear on W6 and on stock. Size the same!
While assembling. After installed CAM, BREATHER VALVE, GEAR COVER, but not TAPPET GUIDE. So there I have two holes thru I can touch gears by finger.
Trying rotate cam - it secure close, and doesn't moving and not producing noise
Then trying rotate breather valve - it can moves a little, and when I swing this gear from side to side, I hear a sound - tic!
I using S&S Breather Gear 33-4250 instead of stock plastic
I'm not entirely sure what exactly is the breather valve produce sound, but nevertheless there is nothing else from

I didn't measure by gauge, but put one spacer to get the same length as old cam. I'm trying move cam in-out by fingers when box assembled, it shows around ~.040 - .070

I believe the book says up to .050" but I like. 010"-.015". Check your timing cup for wear marks.. quick and easy check..

Ok, set the end play to less than. 020"... .040-.070 is not acceptable. You need to start eliminating anything out of spec and .070"is way out..

Checked today cam end play, gauge shows .015" I think It is good result. So I didn't change/add shims
Also putted back HD plasticky breather gear.
Run engine and I no hear bad noise like tic-tic-tic
So this bad guy produce tic-tic-tic noise - S&S Breather Gear 33-4250
I think because this happened with steel, Harley's engineers put there plastic gear.
In future, it will reassembly engine again I'll put S&S Red Breather. It not rotated, and I think not produce noise.
