so is it best to go buy the engine numbers than?

Yes and no. Cooper 'S' engines are a rare sight nowadays. It's quit unlikely you 'bump' into one at random...

But they can be distinguished from smalbore engines via the casting number of the block (back side).
Cooper 'S' engines usually start with 'AEG'. Normal, later 1275 should be 12G1279 / CAM1024.
(with some exceptions, but these exceptiuons don't have tappet chest covers).

I hope all this information doesn't confuse you too much

The above is the only code i can see on the block.

'WFM 1024' would be an A+ 1275cc engine.
Judging by the oil pipe either Metro or 90's Rover Cooper

What advantages does my engine have?

It's red. That's always a good start.

Being a Man United fan, yeh i suppose it does...

Anyway, What advantages does my engine have?

NEVER?!

A & A+ What are the differences?

I'm new to the Mini scence.

A & A+ What are the differences?

I'm new to the Mini scence.

The A+ variants got some improvemnts over the old A series (often refered to as A- to distinguish them better) engines in the very early 80's. To distinguish them form the old, they were named 'A+'. Improvemnts include different bearings, fillet radii (grooves on the crank journals to prevent cracking) and stiffened/ribbed blocks. And gearboxes got bigger bearings, bigger tranfere gear bearings, differentials got improved planetary gear thrust washers to reduce wear, simplified dizzy attachement - that's about all I can think off now.

But it's still an engine design from the 50's...

A / A+ block front:



A+ / A block rear:



Rear shots show 1275cc A+ / A engine block.
The front view shows a 850cc & 998cc block - but same the changes applie. Don't have any better pictures at hand.

Dizzy attachement A+ / A:



And last but not least A+ idler bearing / A idler bearing:



And as a bonus A+ crank (w/ fillet radii) / A crank:
