Voltage regulator upgrade? Keep frying voltage regulators with swap

I've had three failed voltage regulators since making the Hemi swap. First died when I first completed the swap. Second died 2 months ago when at a HPDE event at Texas world speedway. Third died yesterday when running with lights after a HPDE day.

I'm guessing either the duralast part isn't very good, or the 160 amp alternator combined with my high electrical draw is causing issues.

When it fails, the alternator starts charging at full amperage at 18 volts. Yeah, there's 'collateral damage' every time it happens.

What is the most dependable voltage regulator that could be used with the Hemi 2 field wire alternator? I'd like something from a modern day car with a high amp factory alternator, if possible.

The voltage regulator I've been using is the factory replacement for my 73 duster.
