VBelt pulley layout

Noob alert.

I have an LA360 with powersteering, no A/C.
But the current pulleys and waterpump are for an AC car. (4 groove crank, 2 groove waterpump pulley w/ 6 vane pump)
To avoid any cooling issues I'm going to change the waterpump and pulleys.

I'm just a little confused on best layout for the VBelt.

Do I run a 2 groove crank pulley?
1 belt to crank-alt-waterpump
1 belt to powersteering

This kit would work? Small Block Pulley Kit

Or is there a better layout for the belts? Because there are a lot of options..

Thank you for the help.
