I have to get my precombustion chambers out of the head and I don't know if they screw out or how to get them out. Any information would be helpful. Thanks.

Yes, they unscrew after removing the set screw on the side of the head.
Takes a hex tool to undo them and 200 ft.lbs torque to put them back.
Get new gaskets and use plenty of anti seize on the threads. Redrill for new dog point setscrews once re-installed.
