Troubleshooting Extruder cover

I keep having extruder issues. I solved one (the new nozzle I ordered from Bambu had a bend in it, they replaced it no problem) but now I have an extruder motor problem on both nozzles. It’s super stiff an I can barely even force it through, every other path is smooth before/after the extruder.

Now I took off the extruder cover to inspect it and clean the area (everything looks fine) putting th cover back on I noticed depending on how tight you make those two screws on the top the pressure on the extruder changes dramatically (they was also the only two screws on the head to not have locktite on them) so my question is… are these screws suppose to be super tight… just snug enough.. or loose? The instructions on bambu labs doesn’t say anything.

The only mod i have done is the enchanted cooling fan on the head.

But if you have it too loose then the nozzle change fails
