For the cylinder/piston itself make sure that there is no debris from cleaning and you will be fine.
Make sure you remove any liquid or debris from the cylinder head bolt hole as it screw up your torquing overall. you need to follow dealer procedure as far as using bolt dry or applying sealant or maybe a bit of lube.
I would lube every friction point on the lifter/pushrod/rocker that are involve in your rebuilding process. you can use the assembly white grease or any superior product.
Once started let it warm up like 5 minutes to get some oil flowing but I recommend doing and oil change when the engine is warm over boiling hot. There is always risk of having a bit of coolant in he engine from when you remove the head. being said you dont want to run engine with coolant as it does more damage than throwing a hand full of sand in the crankcase.
Hope that help
Having the fuel pressure dropping way over 5 psi is clesrly a fuel supply issue. Knowing you have a good quality filter ( make sure the new one is install in the proper direction) you have to make sure that power supply and ground are correct. Oh those model there is a inertia switch under the right passenger side of the instrument panel. I already had 1 failing in a f150 and that was causing the same issue. Being said if you can have something to bypass it (large cutterpin) than you can test it when the problem.
If you see a change in pressure, its you inertia switch (voltage drop happen so you don’t have 12 volt to the pump) If the vehicle still at fault you are down to poor ground/poor connection at fuel pump connector or a faulty fuel pump.
I would say when a pump fail it work poorly or don’t work at all. So being said. I don’t know how long you are fighting over that issue but it seems it’s like you vehicle has ghost once in a while from what I’m reading. You need to confirm proper supply before calling the pump as it’s a physical job and if you can save time and labor and $$$$
Hope that help.
Don’t get involve into that previous code until your vehicle you main concern is corected. It’s mostly an emission code and require smooth reading all the time to make the computer emission strategy relevant
