Alright here's the deal.
While the engine is cold, or still warming up there aren't any major sounds. Once it gets up to operating temperature I start to hear a BANG sound just about every revolution. I checked the FSM and it says if you hear a knocking once the engine is warmed up and idling to disconnect each injector one at a time. If it doesn't quiet the sound (which it doesn't) then there is something wrong in the heads. The three things it suggest is: really worn lifter, worn cam gear, or worn cam journal. Does anyone have any other ideas as to what the problem could be? I haven't tried listening with a stethescope or screwdriver or anything yet. Any suggestions on what else I should check?

rod knock should change cadence and severity when you remove spark (or fuel, as you have done)
I'll go for the busted lifter, if there is a huge gap that develops, the valve will get slapped pretty hard. Better to get in there before you trash the heads too

That beer you are drinking cost more than my car
I suppose I can make a vid of it.
RS heads would be silly at this point.
It doesn't sound like rod knock.
Good to hear someone else thinks it's a head problem.
