Have you studied the ones on offer, regardless of what years they say they will fit ?
https://www.feked.com/norton-350cc-model-50-engine-gasket-set-1957-66.html

I've got something similar (head) for a project, and it looks like this will fit ?
Also, the ES2 and Model 50 have all the same dimensions, apart from the hole in the middle,
so an ES2 one should fit, although it won't quite come up to the lip of the bore.

If all else fails, it wouldn't be impossible to cut out one from a thin sheet of aluminium ?
They are nothing very complicated...

Enfield head gasket -number 19 in the diagram.
Its smaller than the bore, don't recall by how much though.

[Example of gasket smaller than the bore,for the doubting thomas's. - since all removed]

Amen !
You have to get used to some of the 'characters' shall we say these forums seem to attract,
a little bit of knowledge sometimes goes a long way !!

Having now taken the extraordinary step of looking(!), Rohan’s probably right that a narrower gasket meant for a bigger bore could be ok, seeing as it’s spigotted.

It also looks like one of those designs where you can grind the head and barrel together without a gasket, if you’re into that sort of mod.

Extra-ordinary...

With those oil drains either side, I'd be cautious how a ground-in head would seal.
Prewar engines can do that, because they don't have the oil drains to consider.

Do you have the parts book for it ?
This shows all the bracketry etc, but only as individual pieces, and names of bits.
I'm not sure if this is online someplace, I'd be surprised if its not.
https://www.rgmnorton.co.uk/index/Models-ES2-19S-50-1956_278.htm

Can you do a pic of these pieces, and we can point out (guess !) what they all are,
this is way easier than many words which may not mean much anyway.
And most of the bits will be obvious when you have them in your hand and the frame in front of you.
Most bits will only go one way too, a large set of childhood shaped pegs and holes in fact.... !

If you use the Andover Norton version - https://andover-norton.co.uk/en/shop-drawing/413/single-downtube-s-arm-frame - they also list any parts they have available. I find RGM have a good stock of parts but their search facility is very poor.

Without wishing to trivialize this, this is where all those square pegs and round holes training as a toddler comes in handy !
Exploded views of this stuff - if its not in the manual or parts book it probably doesn't exist, so its a matter of trial-and-error.

If you can show a pic of your box(es) of brackets, we can probably point out most of them.

I'd comment I've assembled several bikes without any parts books or even the spacers,
I simply made everything as required (for the simple round bits)
(stacks of washers make good substitutes for the initial spacings, since you can easily adjust them)
Getting the chain runs correct means the gearbox (and engine) can really only sit in one place,
so everything around them has to be suitably spaced.
Have fun !

Yes you are right Rohan , I am expecting things too easy I will proceed with caution (and a pile of washers)

If you can produce a pic of any problem areas, I'm sure the collective wisdom here can suggest a solution.
And once you get going, I think you will be surprised how readily things 'fall into place', as they say...

Nortons were very similar in how they did things for many years too, so earlier models often provide healthy clues as how later bikes were,
so you are not confined to a narrow band of owners for suggestions.
Its the miscellaneous stray parts that don't belong that are likely to cause some head scratching though - ask me how I know.
This interweb thingy has made that a thing of the past - ask away, and have fun !
