A little back story, because I like to tell a story. Bought a season pass to the drag strip, opening day is today. Fire the beast up this afternoon and I hear a slight knock, most people wouldn't hear it. I blow it off. Get to the track and take a breather and gather my bearings because I'm still getting used to 600+hp, hopping on the freeway I gave it in 3rd gear and I got the "traction engaged" message! Not bragging, but more adrenaline rushes when I drive this car than the 150hp (02 suzuki gsxr 750) sport bike I used to know as the only thing to get my adrenaline going. Ten minutes pass and I get in line, I'm two cars to the tree sitting next to a building with my window down, I hear the knock echoing off said building. I ask the traffic director "Is that me" he replies, "yes". I ask how to leave and he tells me to pull out through an opening, and states "don't blow it up"
We first thought rocker, but it may also be a bearing in the charger. It's not a bad knock, but it got worse from the drive there (20 miles) so I know it is something.
I have yet to tear into an engine, so I don't know much about them. I still have 30+ lbs of oil pressure at idle, I don't think it's that big of a deal, but, like I said, I haven't torn into an engine and have no idea what I'm getting into.
I know my description isn't much to go by, here is a video I took earlier today (before I left for the track). You probably won't hear the knock (drivers side is where it sounds like it's coming from) but I'm trying to give as much info as I can.

I plan to get another video when I take the stethoscope to it to hopefully find out where it's coming from. I don't want to fire it up if I don't have too.
What I know about the heads is:
Ported and polished by BES engines
Patriot Gold Dual springs and Ti retainers
Comp cams 7.450 pushrods with Yella Terra rockers
I will ask the previous owner if he can find out more about who did the work (the guy he bought it from had the work done).
For those who want to help me figure this out, but don't know the car:
