Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

I’m on a phone so maybe the speaker isn’t great but I watched and listened again. I guess I can hear some clatter. I’ll forgo my previous opinion and say there could be some valvetrain noise going on.
I’m about to go rule out exhaust leak most likely, my oil filter relocation hose decided it wanted to be an oil sprinkler and because I would like to maintain my sanity I’m going to pull the header off to get easier access to the ports. I’ll put some sealer on the flange for the header to downpipe and double check my manifold bolts as well
