Just food for thought some of the top all motor engine builders run ls and crv crank pulleys because they are the biggest and heaviest and offer the most dampning.
If you don't buy into that then machine off the accesory belts you are not using. Have it balanced and you are good to go, that is basically what the N! pulley is anyways.
