The plugs quoted on the South-Wales site, NGK BCPR6ES are standard parts you can buy anywhere. In fact they are the standard parts that I have used for years in my Fiesta Mk1 XR2 with the Kent X-flow engine. I have never had a problem with them, and only fit these as I know they work. The car is used as the daily commute/run about, not raced.
If they are the right part, then that is what I will be fitting when I change the plugs on my S2.

Thanks Peter!
After doing some research and checking what type of Bosch plugs that are currently fitted to my S3C, I have decided to go for plugs with tapered seat.
Some research yesterday resulted in the following list of spark plugs with tapered seat:
Bosch HR9DCX (currently on my S3C)
NGK BPR6EFS (like BCPR6ES but with tapered seat instead of gasket)
Motorcraft AGRF32C1
NGK TR5 (like BPR6EFS but with V-grooved center electrode)

I still feel a bit unsure about choosing plugs with tapered seat, but since that type has worked fine on my car before I think I'll stick to them. It seems like they can be a bit difficult to remove though. The Bosch plug I removed yesterday almost felt stuck to begin with, but finally came loose. A local Ford dealer recommended to put some copper paste on the threads when mounting the spark plug to have less trouble removing it. I hope this may be of some help.

Yes, that is exactly what I have found out too. So as spark plugs with tapered seats have been used previously on my car, I will continue to use that type.
Edited to say:
Is there any other way to know what type of cylinder head you have on your car? Like some kind of marking or number? Does anyone know?

Maybe this is not a big issue at all? Seems like both types will work.
I replaced spark plugs (except the front right one which will require a modified socket), rotor and distributor cap last night. And now she runs like a dream! And they say the weather will be nice here this weekend. Can't wait for some driving in the sun!

Both types will work, true.
Only the right type will work properly, and without damage to either the head or the plugs.
You can tell which type you need by looking at the spark plug hole. It's obvious if it has a taper seat (a chamfer round the edge of the hole) or not.
