My kit is hosed
I have a 1986 Romanian G kit built on a Nodak Spud receiver. I take it to a local gunsmith to have them check headspace and timing, just to be sure. Well the bolt will not slide into battery with the Go gauge in place to even check. The barrel needs to be moved forward a significant amount, and probably be regrooved in order to accept the barrel pin.
I am at work currently, but I will supply photos of the problem when I get home.
Press your barrel forwared slightly with the pin still installed. A thousandth of an inch could make all the difference. Did you put the kit together? Was the bolt or barrel face painted?
your kits just fine, just needs a little extra attention is all.
press the barrel forward with the pin in as the poster above mentioned. if that does not work, remove the pin and use a hammer to tap it forward. i find that a press pushes it too much at once as it "jumps" if it is a very tight front trunnion and barrel.
obviously use pennies or a brass bar when hammering against the barrel.
I have a brand new, matching romy g kit (1986 too) that doesn't headspace either. I found out it's the bolt. No matter what ak I use it's bolt on, it won't headspace.
Try a field gauge?
"the bolt will not slide into battery with the Go gauge in place"
STOP. Before you do anything, have the smith remove your FP, and by hand, see if your bolt closes on 5 random new 7.62 rounds - ideally from different lots or mfgs.
It's very well known amoung builders that US 7.62 GO gauges will often not chamber on Minimum Headspace AKs. 99.999% of the time, factory ammo will chamber very nicely. In fact, a number of us CHEER when we get a kit this good.
Just an FYI, almost every G kit that I've had won't close on a "GO" gauge. It will close on a live round (firing pin removed from bolt) though. Will yours close on a live round? I've had no problems with my build whatsoever and if you do some searching here and on other AK boards you'll see that this is relatively common. If it won't close on a live round (firing pin removed) then you have an issue that needs to be corrected. I believe the reason why so many won't close on a "GO" gauge is that the gauges most people use are SAAMI specs where in Europe they use CIP spec gauges which are slightly different in dimensions.
See above... Your kit is fine.
Where do you get the Non-US gauges?
I'm sorry.. I've never used a guage on any of my matching kits..
Like above, I just pull the FP, and check about a dozen rounds.
If all goes well, it's BANG time...
I came across one all matching '74 kit that the bolt wouldn't close on an empty chamber.
I put the rifle in a vise barrel down and gave the breach a couple of taps and *presto* all is well.
I would have bet against that little stunt doing anything since the barrel pin was already in but then I would have been wrong!

I believe Manson makes both CIP and SAAMI spec gauges.
Ok totally crazy. It will go into battery with an actualy round. You guys were right. All I have on hand though is some Wolf to test though. What does this mean?

It means that you're fine.
BETTER than fine. You ended up with a very GOOD kit, at minimum HS. Recheck once you go to the range & fire some rounds thru it... and try to collect the first 10 or so empty casings. In particular, feel for any buldges in the casings about 1/8" forward of the rim, and look for split necks.
Sounds like the barrel was either pressed in too far or you have a "like new" kit that will gauge better after a few hundred rounds. But instead of guessing I would trace the steps and be certain as I have known some who lapped the bolt for this kind of problem when the barrel was pressed in too far and when the barrel migrated back the headspace was too much (still safe but that much closer to wearing out). Ironically I have not met a gunsmith familiar with the AK system (and I have met several accomplished gunsmiths).
I only bought a no go gauge as I use live round as the go gauge
If she closes on the live round and doesn't close on the no go gauge, you are good.
And yes make sure to remove the firing pin
