BBC Crank and WP Pulley Options

Looking to put deep groove pulleys on my car. Its a 427/L88 in a 55 Chevy. I currently have 66 BBC 396/325 Chevelle pulleys on it. I have two WP pulleys and two crank pulleys to choose from. What would be the best combo between these pulleys.

WP 3906656 and 3770245
Crank 3899660 and 3863108

The wp pulleys are the same od. The crank pulleys are a little different in size.

Thanks, Larry
