I've watched every video several times.
Appears that the tap in question hasn't changed since day one.
Appears that it's a single tap..NOT 16 that would indicate some kind of geometry problem.
(FWIW) The original rockers have at least .060" clearance, at the closest point, between the poly hex and rocker body.
(FWIW) The original rockers have no shiny witness marks that would indicate bottoming out in the bottom rocker slot or against the poly lock.
If and BIG IF one of the lifters isn't holding pressure....Engine running, find it by pushing down on the rocker with the palm of your hand (at the pushrod). Then I'd run the poly down to see if you can quieten the tap noise.
If BIG IF it does have a bad/leaky lifter, I'd go as far as setting the lifter .010" or so (cold) "from bottomed out" and get some drive time in untill that lifter can be replaced.
If it is a bad/leaky lifter, replacement here would be ahelluva lot cheaper than shipping to and from AZ.
Oh so slightly bent pushrods are not causing this "SINGLE" tapping noise.
Need new eyes, new hands, or something to get this tap narrowed down.
Don't know who wants this figured out and fixed the most...Joe, Paul or me.
