If it were mine, I'd replace them all.Good call on the lifters from Larry.
If you determine it is a lifter, use what ever brand and install limiters in them.
So you buy shoes one at a time? Lol...remove any doubt or guesswork and replace them all. It's a relatively cheap fix in the world of harley
Do like KD suggested or a screw driver with handle against your ear and tip against the head. Not going to be 100% certain as to which lifter, but will isolate to 50% of them... Lifters are easily disassembled and cleaned. But, some lifters are just crap out of the box (HD C's). You have check balls or check disks, also the retainer can get dislodged. Larry's lifters are very reasonable option for the money, worth giving them a try. You can then evaluate yours and decide if it's just one with issues or many. Possibly get some warranty love from Woods if they are defective and you find they are clean. IMO CR-570 is not extreme. Harley -C lifters will clatter at start up with stock lift, -B's (NOS if you can find) can take a lot of abuse and would work fine with your cam.Are the temps where you live getting really low?

A question for the smarter ones here, would it be possible to tell which lifter is bleeding down by checking the pushrods cold? Would it bleed down enough for one to be noticeably loose? Maybe check warm, then check cold for any difference. Or do they not really loosen up that noticeably?

Using 32 TPI push rods, 1/2 turn, the most the lifter can bleed is 0.016" with the motor cold.I run them in my 124", use a stock cheap battery, stock battery cables, and a 1.4kw starter. It turns over no matter how cold out or how hot the motor is. And no valve noise.
I use S&S w/ limiters. Now with the rumour out there that the S&S premiums are a different manufacturer now, I am wary of buying them. I am coming up on the 30,000 mile recommended change cycle with my spring weight and wish I would have bought them for on the shelf. It's all quiet about Larry's lifters and they seem to be top performers. What to do???
