MA12 REAL specs

Hi!
I'm oppening this thread to ask you which are the real specs for the MA12 engine, specialy the max power rotation.

In Haynes book they say that is 60hp at 6000rpm.
In some sites in internet I see references about 5600rpm, 5200rpm, etc.

In which I should bealive?
Must say 6000rpm is way huge in an engine like this.

Didn't know.
So, you can explain to me the diferences?

mad dragon, it might be something to do with u-cat/+u-cat (unregulated ?)
autodata says 60hp @ 5200 for the u-cat
and 60hp @ 6000 for the +u-cat
same dcz306 carb, same 9:1 c/r, same transistorised ign etc :)
 
I have to say that I didnt understand yet what is the "cat".

cat = catalyst?
If yes, I supose only the catalyst K10 have ECU right?
So, 6000rpm for this one has you said right?

Sorry for the questions, but Im not english and I dont understand the sentences at 100%.
