Motor help please....Coyote ticking

[ClemsonS197]

So I'm at a loss. The drivers side of my motor has a serious ticking. Originally I thought it was a gasket leak. But I guess not. Here's what happened.

Installed Factory Five headers and J-pipes. That went smooth. Drivers side sounds fine as shown in this video:

Then I pulled the FFR headers for the Stainless Headers. At first the motor only ticked at idle on a cold motor. Once it got some heat, the tick went away. Then they started to tick constantly. So I ordered new gaskets, pulled the headers and reinstalled. Now it still sounds like this:

I pulled all the belts off the motor for a second to see if it was the infamous Coyote pulley tick and no change. So then I pulled the sidepipes off and just left the headers on and it's even louder. The drivers side also backfires like crazy.

The entire time I've had the radiator and cooling fan operational. So I wasn't running the motor dry. I also have no heater bypass so it flows coolant constantly.

Anyone have any ideas? Thanks.

For record keeping, the issue was 2 bad spark plugs.

After swapping the coil over plugs from passenger side to drivers side with no change, I started to disconnect each individual pack while the motor was running. Cylinders 1 and 4 of the drivers side had zero change on the idle and tick. Any of the other 6 cylinders changed the idle to very, very rough. I figured there was issue with spark. I pulled 1 cylinder plug out and attached it to the coil pack. Grounded the plug against the chassis, started the motor, and nothing. Did this same with cylinder 4 and nothing. So I pulled cylinder 3 and it sparked perfect. So I swapped spark plug 1 to 2, 4 to 3 and vice versa and the rough cylinder issue moved to 2 and 3. Bad spark plugs. Chased my tail all weekend to find $10 worth of spark plugs ruined my to do list. Can't complain too much, at least it was a cheap fix.
