Help, i am stumped!

Hey everyone, Im hoping someone has some ideas on this because I am out of them.
I have a 03 Ram 5.7 with 190k. It started giving telltale vapor a couple of weeks ago so I tore it down and replaced the head gaskets and valve seals. I figured I might as well put an oil pump and timing chain while it was down so I did. At this point, it has a new set of head gaskets, new head bolts, new plugs and wires, and a new oil pump. Now, when I crank it, it fires right up but idles rough. I thought maybe I crossed some wires so, with the engine running, I began pulling the coil pack leads off to see if they were getting fire. I pulled every wire off all four on the passenger side and never noticed any fluctuation in idle, or tone. So, with only the drivers side coil packs plugged in, the truck stayed running with no popping or spitting I would normally associated with timing being out. BUT, it will not pull as it should ( while holding the brakes and flooring the throttle it would not break the tires loose even on a wet driveway.
I just ordered a new cam and crank sensor as the truck is throwing a P0016 code. Has anyone got any ideas? I triple checked my timing gears were at 12 and 6 with the proper links pointing where they should. I dont kmow what else to check. Help!

I would see if the cam and crank sensors take care of it before trouble shooting farther.

From what you have said I'll guess you have the cam mis-timed.

The wires that run from the coils to the other cylinders are the waste speak wires they don't fire in the compression stroke the coil itself fires into the hole its ontop off. When you say you unplugged them do you mean the wire or the actual electrical plug?

The p0016 code is a correlation code you may have mistimed the engine here the cam gear had a dot and the crank gear has a dot not the keyway it sits around 2 o'clock range if I remember correctly

I am referring to the pigtail supplying the coilpack, not the 7mm plugwire.

I did think that but, everything went back in the same place as the old. But. If the cam was off time, wouldnt tje engine spit and or backfire?

Im hoping that takes care of it. I pulled the cam sensor yesterday and cleaned the comtacts off hoping maybe the degreasing I did may have just gummed it up but, no luck. Ill update when i get the new sensors.

I assume that would retard the timing enough to cause lag but not enough to misfire enough to spit or backfire. Hopefully the sensors will be in and I will know it all out. Ill update when i do.

As I take stuff apart and more importantly as I put it back together I take pictures so if I have second thoughts I can check to be sure what I did.
