A "Go" headspace gauge is used to verify that the chamber of a firearm is large enough to accept correctly sized ammunition. When a "Go" gauge is chambered in a firearm, the action should close normally, with no unusual force.
That is only half of the information needed to verify the headspace is correct, however. To verify that a firearm is safe, both a "Go" and a "No Go" gauge must be used.
The "No Go" gauge is slightly larger (usually about 8/1000 of an inch), and is used to verify that the chamber is not too large for the correct ammunition. If the action closes on a "No Go" gauge, the headspace is too large, and it may be dangerous to fire the weapon.
Headspace refers to the space between the top of a liquid in a bottle and the cap. It is important in packaging for product stability. Headspace can be recovered by removing some of the liquid or gas in the bottle to achieve the desired headspace level.

Are you talking about a browning model M-2 heavy barrel machine gun?If you are these machine guns were issued with a timimg and headspace set of gauges that were used to set the correct head space and timimg.I would start with screwing the barrel all the way into the receiver.Then turn the barrel back out 2 clicks.Then by using the operating handle on the side of the reciever,pull back enough to insert the head space gauge with the no go end in first between the breach block and the reciever and let the breach block go forward.Then press down on the butterfly trigger on the end on the reciever and see if you here a click of the firing pin releaseIf it does not repull the breach block open and invert the gauge with the go end inserted and try the steps again.If the firing pin releases then you have the proper headspace.If it does not then you will have to turn the barrel out 1 more click and repeat the steps mentioned.If the headspace is set properly then you can go on to the timing gauge and try the no-go end of the gauge first.If there is no click then invert this gauge and use the go end of the gauge and repeat the process.If you here a click of the firing pin going forward then you have the timing set.These steps should be followed or you will rupture the reciever block and it is possable to kill the operator of the gun.I am recalling this from 38 years ago as i was assigned a browning m-2 heavy barrel when I was in the marine corp.

You don't. You headspace AND time the gun, because the timing changes with headspace and the headspace changes every time you change the barrel. This is from the Picatinny Arsenal: To headspace the weapon: 1. Raise the cover all the way up and retract the bolt. 2. Screw the barrel all the way into the gun, then back off two clicks. (To tell ya the truth, this is where most guys stop when they're in Indian Country.) 3. Charge the weapon and ride the bolt forward. Don't let it slam home; since the gun isn't loaded, if you do that you'll damage the bolt. 4. Retract the bolt about 1/16" and hold it there until you've used the gage. 5. Raise the cartridge extractor, push in the alignment guide and try to put the "go" end of the headspace gage in the slot between the face of the bolt and the rear of the barrel. There's a ring on it. If you can get the gage to go in all the way down to the ring, pull it out, turn it around and try to put the "no go" end in the same place. If the "go" gage went in and the "no go" gage didn't, you're done. If the "go" gage didn't go in, unscrew the barrel one click and try it again. If the "no go" gage went in, screw the barrel in one click. Keep doing this until the go gage goes in and the no go gage doesn't. To time the gun: 1. Set the headspace. 2. Raise the cover, charge the weapon and ride the bolt forward. 3. Retract the bolt far enough to put the "fire" gage in. It goes between the front of the bolt and the back of the barrel, with the beveled edge against the barrel notches. 4. Remove the backplate and screw the timing adjustment nut down all the way. Don't take it off the timing stud, though. (This is where timing this thing gets tedious...) 5. Retract the bolt far enough to remove the fire gage. Reinstall the backplate, retract the bolt, stick the fire gage in and try to fire the gun. It shouldn't fire. 6. Take the gage out, remove the backplate, screw the timing nut in one notch, put the backplate back on, the gage back in and try to fire the gun. Keep repeating step 6 until the gun fires. 7. Remove the gage, remove the backplate, screw the nut in two more clicks and put the backplate back on. Charge the weapon and ride the bolt forward. Insert the "no fire" end of the gage and try to fire. It shouldn't fire. If it does the gun has to go to the shop. If it DOESN'T fire, turn the gage back around and try to fire again. If it won't fire with the "no fire" gage in and will with the "fire" gage in, you're done.

Passive headspace diffusion is a process in gas chromatography where volatile compounds from a sample in the headspace above a liquid are absorbed onto a solid-phase microextraction (SPME) fiber for analysis. This technique allows for the extraction and concentration of volatile compounds from the headspace without the need for heating or agitation of the sample.
