I hate to advocate drugs, alcohol, violence, or insanity to anyone, but they've always worked for me.

This is the new "high speed/low drag" mod all the serious AK operators are using now. More gas pressure = MORE POWER
The unvented gas tube and gas block would have little effect on the gas flow/pulse.
The gas pulse is in fractional second duration.
What’s the diffeeence between an akm and ak47 gas system(other than gas tube vents)?
Russian Type 1 or 2 parts/kit
AK47 is vented in the tube., AKM vented in the gas block.
OP's picture shows no vents.
Not a real issue in function.
Some of the current Saiga's are totally unvented.

It probably just ejects the shells at a slightly faster velocity and hits the trunnion a little harder. It wouldn't have any effect on bullet velocity because even in a vented rifle the bullet has long left the barrel before any gas would vent out of any gas ports.
Now the extra force on the bolt would increase felt recoil a bit, and I imagine that the gas tube would get a lot hotter because the gasses wouldn't have anywhere to vent other than back into the receiver. So you'd just be making the weapon a little more uncontrollable.
There will be no additional force on the piston or carrier.
The gas pulse is in microseconds.
The fluted gas tube has no capacity to create gas pressure.
The gas force is created inside the gas block in the short distance of the forward edge of the piston to the gas chamber in the block.

That gas tube looks like it is so tight onto that gas block that I bet it couldn't be removed without pressing the block forward. On the plus side, no wiggle in the gas tube.
If gas ports serve no purpose then why were they put there in the first place?
Doesn't make much sense to add another step in the design and production process for a completely useless feature.
I'm assembling some leftover parts for a Khyber rifle ATM and I'm using the exact opposite setup pictured above - a vented Romanian AKM gas block and a vented Hungarian gas tube. I doubt it will mess anything up since the Hungarian AKM's were built like this from the factory. Either the Hungarians were trying to bleed off more gas or just felt like producing gas tubes with rows of vents in them purely for aesthetic purposes.
An AK will operate the same without the gas tube. There are videos on the www.
The Hungarians did not fully adopt all of the sovietAKM changes.
They kept the AK47 vented gas tube and adopted the vented gas block.
They did not adopt the lightening mill work cuts on the gas block or the front sight base.
It seems that the venting of the gas system assisted in heat dissipation.
