The other thing it could be is the front exhaust pushrod hitting the inside of the tube. It seems fairly common with the S&S Quickee pushrods and tubes.
The adjustment collar part of the pushrod above the locking is quite thick and there's not a lot of clearance between that and bottom of the top part of the pushrod tube.
Nitrusfix suggested a solution in my thread here which worked for me:

But - try just readjusting the pushrods first....

Since there seems to be no base maps for the fueling 574's and PV2 (the one on the fueling website is not functional), I've taken some advice at HTT and simply increased the engine displacement by 10% on my Andrews tune and will do some auto tunes to get me to the dyno guy!
Will let you know how start up goes.

If it's not the PR's maybe give Kirby a call and see if he sunk the valves when working on the heads and if that could cause a knock with your cams. .doubt this is the issue since it only sounds like it's coming from the front cylinder and not both cylinders but I recall sometimes the upper rocker covers require clearancing.

Having problems embedding video but...
BUTTER BABY!
Adjustment seems to work, sounds beautiful and rode to work smooth although I haven't opened it up yet. Going to autotune for a bit and hope to get the dyno scheduled.
Hoorah!

While I didn't post any good pics or learnings from this most recent mod I will say that other than super tight fitting areas it's really not been that difficult.
Used the Service manual a ton as usual along with the expertise of so many of you who have done this before.
1. Throttle body removal and installation sucks, nuff said on that.
2. Save time in the future, I'll just take the heat shields off the exhaust prior to removal of system so that I don't spend so much time trying to wrangle stuff.
3. Dogbone attachments to get to hard to reach places (like the rear cylinder) are a must, I won't deal with that again without them.
4. Working in 45min-1hr increment sucks
5. Remember to bolt down the cylinders once the heads are off so that you can rotate the pistons for cleaning.
