Default Ls/Vtec piston question....

Okay, I'm apologizing right now because I'm sure this has been covered before, but my searches came up empty.

I just picked up a B18C5 block and after reading about the C5 crank, it's heavier than both the LS and the GSR block, so I'm ditching that in favor of an LS crank. (I know the differences between the cranks and revs and all that) I know I have to use LS rods, but what pistons do I have to use:

B18C5 block : LS Crank : Ls Rods : ??? Pistons

You'll enjoy the additional 25ft/lbs or so of torque from the LS crank than anything else. The Type R, and GS-R crank weight differences are negligible in a rotating assembly that is turbocharged. In these applications, that is the only difference

Right. So just to be sure, I can use any aftermarket B16/B18C pistons?

Nice, I'll be sending my block to earl for the sleeves anyway, so might as well get the pistons from him
