Default B2x crank pulley / B230 harmonic balancer

Does the B23 crank pulley have the same bore diameter as the B230 harmonic balancer?

I remember Nathan used a Toyota 7M harmonic balancer when he converted to serp driven accesories. I see the 4AG has a 2 belt 5 groove pulley that might work for the same purpose .

I am trying to see what that bore diameter is for the redblock and determine if they are interchangeable.
