Is there a video for using a No-Go gauge in a VZ-58?

I'm only curious because my first gauge arrived, and >>>  3 of my 4 imported AKMs <<< had excellent results. Was is a new ZPAP, the others used a moderate amount of ammo.
*Rob Ski's "head space" video for the No-Go was  :)very helpful as a guide.

No luck with Youtube, but I'm simply curious how it is done in a VZ.
It never hurts to check something. This Czechpoint was nib in 2019, has seen 2,500 rds. The gauge is a Clymer 7.62x39  bought from Brownell's.

Both CIP and SAAMI 7.62x39 chambers -- need to use the correct gauge. 

If you search this forum, you'll find instructions checking headspacing, including removing the extractor.  Not aware of a video.

Thanks RSR.

Being curious hours ago, I placed the No-Go gauge on the bolthead, allowing it to slowly close with light pressure.

This might not be an approved method, fwiw (if at all)  the forward edge of the bolt carrier remained about 3/8" from the normal closed position seen while in battery, both times. Seen from the upper recess of the carrier.

Off the subject, but my MAK-90 (AKM: bought barely used), which has burned up approx. 2,000 rds. of my ammo Failed     the Clymer No-Go gauge from Brownell's.
That's why I've checked my several rifles in 7.62x39, and today ordered a Field gauge from Toth Tools to Closely monitor the MAK for limited use - IF allowed by results of the Field gauge.

RSR is right, CIP vs SAAMI chambers are slightly different so the gauges will be slightly different, and a clean chamber and bolt face are important.
I’m not a builder but follow a lot of them, and the consensus is go/no-go gauges are for setting headspace on a new build, field is for determining excessive wear on an existing build. A lot of parts on the 58 platform affect headspace; carrier, bolt, locking piece, etc… Headspace can be adjusted (or screwed up) by swapping in parts. For example locking pieces have a number electrostenciled on them, supposedly for size. There was a thread in the past that discussed this, in that which pieces affected the tolerances the most and which the least. I’d think anytime these parts are swapped around or replaced that the headspace be checked.

NativeTexan: Most of what you mention is exactly what many rifle builders have described (AKfiles, Youtube etc).

Being recently retired I've read so much about guns and head space, waiting many hours in hotels by ATL Airport to then fly a 'trip pairing' the next day. I admire the guys with both the skills, equipment and the time invested in order to acquire the technical proficiency to build guns known to be much more difficult than an AR.

Your comment about not changing anything which affects headspace reminds me of the unbelievable Frankenstein marketed years ago by Century Arms, done by a contractor; the "AKM" experiment, known as the MISR 90. Some people get confused by the 90, also used to designate some of  the MAKs.

Century's contractor company checked MISR 90 Head Space, but on a number of these they then Swapped barrels, but No Second head space check was performed!
A gun shop owner in Clarkesville TN said that a few of his MISRS had "bad blow outs" (!!)    after customers tried their rifles.

This dealer on Ft. Campbell Blvd (7-9 years ago) didn't know a Maadi from a MISR 90, therefore wouldn't touch any more of either designation.
