I think there are two issues here.
First is stock + optic height and second is shooting stance.
To the former -- on ARs there are increased height risers for red dots, both mounts and risers and folks are increasingly switching to those from cowitness options.
Here's a riser from unity:

https://youtu.be/84KBHdpKB1cFor second on stance, this video is great -- basically transitioning from traditional bladed stance to modern squared fighting stance:

I have a half dozen SF Brakes remaining (listing in classifieds), but there are other options w/ more flash and blast as well that also tame recoil and increase muzzle control.
For me, I use the low inline NEA forward red dot mount combined with a more aggressive shooters stance that pulls my head down (think linebacker stance but leaning further forward than I would w/ an AR) -- I'm 6' w/ a 34" or 34-35" dress shirt sleeve arms and a longer neck. For me, the standard stock length works well w/ body armor or winter clothing, and adding the AK grenade launcher pad works great optimal length with a tshirt -- and they also fit on fixed stocks. Like this pad:
https://www.desertfoxsales.com/RUBBER_BUTT_PAD_p/dfs-207.htmTo the VZ58 specifically on the first part -- it does look like you could use a taller/higher stock and with an adjustable length of pull, but you need to be okay w/ not comfortably using the factory irons w/ these revisions -- could look into offset or qd optic removal for straining into them in emergency, but not for regular use...
So to fitting to a larger shooter end on the stock side, you really only have:
- the Stormwerkz adjustable adapters that are best suited for AR-style stocks -- ace stocks sells a buffer tube adapter that screws in (you're building up here and each connection offers some level of adjustment, so could potentially omit the folder, but I would recommend against that if you can afford it)
http://stormwerkz.com/stock-adapters/vz-58-stock-adapter-type-3-straight/ (could use angled for folks who just need minimal add'l height, but straight better for recoil control too -- Rifle dynamics uses something similar to this for their AK builds) +

https://www.carolinashooterssupply.com/ACE_CAROLINA_SHOOTERS_AR15_STOCK_PIGNOSE_ADAPTER_p/css-pignose-noboss.htm- the RS regulate adapter for the Magpul Yugo stock (Yugo stock has a few different snap on cheek riser heights available, but polymer hinge so slightly less robust than stormwerkz option)
https://rsregulate.com/product/vzsa/- Or this FAB stock w/ a quite adjustable cheekrest -- believe they offer both polymer and steel (something like +$100) hinge options for this stock, or maybe just for their AR ones, which is another option as those also have cheek risers but the risers look less rigid:
https://zahal.org/product/fab-defense-sa-vz-58-tactical-folding-stock-cheek-rest/*I thought that FAB had adjustable LOP, but it doesn't appear to -- their AR style definitely do, but uncertain about the utility of that cheek rest:
https://zahal.org/product/fab-defense-m4-folding-sa-vz58-rifle-stock/For increased height optic mounts your options are greater:
- RS regulate side rail mount with several different height options for upper rail mount
- Czechpoint side rail mount that sits higher than RS's lowest VZ58-specific configuration -- if the CP version fits you
- railed top cover mounts all sit higher than factory irons, but generally lower than side rail mounts
- the Scout Optics scout scope mount that replaces the rear sight and is probably the cheapest option and is probably the tallest option short of sticking a riser on the taller forward handguard mounts
- the forward taller upper handguard mounts -- the B&T (unsure if currently available) and the DForce rails that vz58rifle US sells are only two that clamp to the barrel for optimal stability as far as I know (NEA and Bonesteel lower-mounts both use set screws off of gas block and receiver for repeatability instead), and the FAB Defense aluminum version might clamp but uncertain
--- Of note, I think DForce makes and sells both rear railed top covers and railed front handguards that are properly inline for offset irons use if that's important. Uncertain if anyone else offers this capability/matched configuration offhand.
- and finally, you could use any standard picatinny rail optic mount option with picatinny rail riser(s) stacked atop that are available in varying heights
And don't forget obvious considerations of height of optic over bore as you raise it, especially for very close self-defense situations where civilian rifles are most likely to be used.
Hope this is helpful.
*And here's the Rifle Dynamics AK stock mount for comparison -- unfortunately they don't offer this for Vz58s:
