Those cam specs were from my (genuine) manual. Although I was tired I am sure they are as printed (but will check tonight). Can anyone else confirm? I am not such an anorak that I always have it in front of me.
 
Btw - for the record, I have driven both genuine and aftermarket 4BD1Ts. IME a properly set up aftermarket conversion drives as well or better. There is a lot of room for improvement over the original design. e.g:
Intercooling
Better intake and exhaust routing/flow (as John said - better manifold(s)).
etc.
