have the same dam noise in mine in the same rpm range, same cam and headgaskets as you but in a l67, made the noise before the cam swap, put new lifters and cam bearings in at the time of the swap and still has it, also measured lifter preload and got that all good and still have the sound. mine first started making noise about 5000 miles after a complete rebuild, put about 500 miles on it since and hasnt gotten louder or come apart

I know this highly unlikely but did you check piston depth vs valve clearance since I saw u went to a thinner head gaskets and a cam with more lift might be the valves slightly tapping one of the pistons from bad grind on 1 of the lobes, throwing another idea out there
