Really makes me wonder if you don't already have serious lifter roller and cam damage.
I live in colder clime, use same lube package, and do not have the issue.
I understand you are in damage control mode and looking for faster cold start lubrication. I'd encourage you to employ a prelube strategy now when it's cold - hold throttle wide open, go through 3 crank cycles.
I think there's plenty enough evidence on the forum Hemis require unique lubrication strategies to not self-destruct, and Red Line can only save so much if damage is advanced too far. Which is why I switched to Red Line before audible damage occurred.
Best of luck!!
