Clack clack clack
I finally spoke to the po .He wanted to buy the car back lol He bought a new Raptor because his wife is expecting) and he said the heads were done at american heritage with their #4 package with btr springs and retainers and kept the stock cam/lifters about 6000 miles ago. I hate hearing that tick!! I seem to hear it better when I'm in the car coming to a stop or between shifts when engine is idling down. i hear a clack clack clack not super loud but i hear it.

Injectors?

Agreed...easy to do. Pull the covers and make sure everything looks clean and tight. I'd say inspect for lash caps...but at 6,000 miles since the head refresh, a Ti intake valve would've been hammered into a cylinder a long, long time ago.

Is it just one on one side or all of them? If just one it shouldn't be to hard to figure out which side it's on. Pull the cover on that side first and inspect. Not knowing the piston to valve clearance on your setup, this might not be the best advice but if I have one that is noisy, I use a .001 feeler gauge and slide it between the rocker and valve stem while running to find the loose one.

Pushrods aren't going to cause any noise unless they're too short, most likely what you have is a bad lifter

sounds like pass. side at 1500-2200 rpm when loudest
