Hello everyone!
I'm here for a smidge of advice, where ever I can find it. I have a Gen 1 coyote which I just recently pulled out (mainly for TKX swap). I mostly focused on heads and timing. It got new lifters, MMR springs/retainers, billitt oil pump/crank sprocket, pickup tube, windage tray (truck variant), polished journals, and all new Cloydes timing set, which I thought was very easy to install with the timing marks.
Bad news is after a 5 second test start and getting everything else bolted up, I now find that it has a mechanical tap to it. Passenger side. Runs as fine as it did before, but this noise caused me to turn it off fairly quickly. Got louder when the oil cap was opened. A few things come to mind.
When turning the motor after timing it, I noticed the passenger side chain slapped every rotation, on the non-tensioner side. I chalked this up to be the tensioner not having oil pressure in combination with the strong MMR springs pulling the cams back to a closed position. Perhaps it was a mistake to turn to OEM replacement tensioners with upgraded springs? I am certain I took the care to time the motor properly.
Otherwise, all I can think of is needing to run the motor for longer to get oil everywhere in the system. The longest I've let it run is maybe a minute or two, I am afraid of wrecking my freshly redone heads. I primed the motor every time I turned it (via garden sprayer) and before the first start. I also have an oil pressure gauge that reads normal. Maybe the lifters or tensioners need time during the first start?
Already took the cover off and looked for loose parts, none on the head. Anyone have experience with this?

Thanks in advance.
