I would wary of fitting high lift cams...you can only go to approx 256/260 degree cams before the
management system throws a wobbly.
So assuming the came are 256/260s, look at the lift - if there is a bit gain in lift, you may be OK...but if
you are keeping the lambda sensor and Cat, and want it to be legal, it's a minefield when fitting came to an
ABF.
Assuming you do get cams to run, all you will do is move the torque up the rev range...you will get more
power, but lose low end torque.
Some of the aftermarket cams are designed for KR or ABF and in reality, aren't much more aggressive than
standard ABF cams...so an utter waste of money. That the sound advice I have been given
