Risks of Running High Amp Alternator?

Again, really appreciate the information posted here.

I have been looking into this further and found some pretty decent Powermaster alternators that may meet my cars needs. I am seeing that most of the higher amperage ones are internally regulated, and from what I understand are the single wire style.

Example:
Powermaster Street Alternator

Currently I am running a 2 wire Squareback, externally regulated with my voltage regulator mounted on my firewall.

If I made the switch, how would this be wired? I am assuming I take my existing VR out and the new alternator would take care of all that?

Again, just being cautious to not burn up my car!
