I see no carbon around the plates, one thing I haven't thought of though is the EGR tube where it goes into the collector. That weld may have broken due to vibrations. I have a few things to check, I'll report back IF i find it!

I replaced my plugs and wires yesterday being very carefull, and it seemed to help a bit, even though it's probably in my head. I used new NGK tr-55's and OEM LS2 plug wires.

The wife's car is at the tuners getting setup for the cam. As soon as it gets back and I get some free time from work, I'm going to dig into it more. I will find the source of that tick if I gotta tear the whole thing apart.

Well, I officially give up. Header bolts are tight, collector bolts are tight, plugs are tight and I see NO carbon and can find NO leak. Must be internal.
I just did a H/C swap on my Formula and I think I have the same tick that you're describing 
I'm hoping my lifters are ok (stock re-used).
I called Texas-Speed where I got the parts from and they said that if it sounds like it's coming from all over the motor it's probably valvetrain noise that you'll just have to deal with. If it was a "tick" that was coming from a specific point then it could be a loose rocker or a bad lifter. Since it has that general "sewing machine" sound....there's nothing you can do about it.
They said they've tried solving the problems with cars that have gone through the shop with different length pushrods and it's not helped.
I sure hope it gets better though.....not a big fan of how loud it's ticking.
Other H/C cams I've heard were not as loud

Rockers are tight, I checked around all the Y pipe connections and header flanges and I can't find any black soot. Everything is tight on the exhaust and I cannot find a leak so I'm guessing it has to be a lifter. It's only noticeable on the drivers side near the rear of the motor.

Well, after a nice long highway trip, I see some carbon by the #3 and #5 primaries so I'm going pull the header off and check that. I hope that is the source of the leak!
I'm almost convinced it's a leak now also, after logging the car on the trip, the LFTF's are different for both banks which suggests an exhaust leak.

Thats great to hear,man !! I plan on changing my plugs and wires this week as well. I hope this will cure my ticking sound as well. I do belive one of my wires are arching and causing the noise. I still have the stock wires on . They will be replaced with a set of Taylors wires and NGK TR-55's !!
