Installation procedure calls for 44 in-lbs on the first pass, then 88 in-lbs on the second pass.

Also included the lower intake pattern just for fun which get's torqued to 72 in-lbs first pass, and 10 ft-lbs on the second

Yeah. I pulled the lower intake with the engine still in the truck once. I have mad respect for guys that do cam swaps without removing their engines lol. Things get a little tight at the back of the engine but it's not that bad overall. Upper intake coming off is really easy imo.

Ya I pulled it today what do you know about the fuel pressure key on ignition off I’m at 45 psi and it drops to 40 psi it’s gotta be the fuel pump but it starts and runs fine

Haynes is good, better is the service and unit repair manuals are all here, complete, OE original, in pdf format, and free to download. Never have that " hmm is that really how that goes ?" , Iffy thoughts.
From the poeple that designed, engineered, and built it! Good luck.
