16v battery on hei ?

Running a b-mod with HEI distributor. Is it worth running a 16v ? Is performance better?

Run a alternator. ,didn't think u could run a 16 volt battery in that class

If youre in IMCA you can't run 16volts.

Just wondering if 16v is too much for an HEI module? Should you run a step down box with 16v? Not an IMCA car!
