dont know the torque but tightening them by hand wont be sufficient
you need man tools like ratchet bar and socket things
i always tighten till they feel right

25 Nm is the going rate but as the man says a lot of 'feel' is needed cause they get corroded. The 25 might not get them tight I give the threads a rub of a wire brush.

3 of the studs remained in the head, and the other 5 all came out, i was using a socket and ratchet but didnt think it was tight enough onto the head, i nipped them up tight,
might just try exhaust paste (i know i shouldnt but it it doesnt seal then it's invest in a new manifold anyways) on the manifold side,
Puntistas.............. :bang:
Soak the ones that came out in penetrating oil. Use the old locknut trick to release the nut. Degrease. Re-insert with locktite. If you must torque them up, 24nm is the figure given in all the manuals (strange books that some people buy before working on cars, but what do they know). .

But if you know what your doing then there's no need to buy a manual for one tiny figure!! I had a mk1 1.2 so its the same engine except a reworked head to accept the injectors!
But then if I didn't know this I would of been asking the difference between the 2 heads!

Torque and preload....watch out if you're using washers or grease.....
Be careful of the ones that come out of the head. Nuts tend to wander down the stud so when you put it back in there is insufficient engagement of the stud in the head. The stud should go in at least one and a half times the stud diameter to be sure that the full strength is available. Tightening up with just a few threads in can strip them at the specified torque.

Lots of oil - lots of heat
Stick the stud in a vice - and wing the nut off
A good wire wheel to clean rust off
You can try using a Wire style edged file to clean the thread to in hope to make it easier to remove

I know this goes against all Punto traditions of keeping hands out of pockets, bodging, etc. BUT, you can buy new, replacement, studs and nuts, take my word for it.

I know fiat do them - but is there anywhere nearer and cheaper?
I was going to get some nice new rear drum ones but decided against it

Ah, wheel studs? Rallysport and others do them. 90% of the wheelstuds you see for sale are made by one company. Fitment (if not length) is same a Subaru.
