Default Pistons for a stroker

I recently picked up a 4 inch stroker crank for a 350 chevy 1 piece seal block. I'm going to run 6 inch rods. My question is there a manufacturer that makes forged pistons in a 2618 alloy for this combination. Otherwise, I'm going to have to pay big money to have them custom made.

A couple local engine builders say it can be done. The 1 piece blocks have more room for a stroker. The new zz4 crate motor has a 3.800 stroke and has no clearance needed. What's another .200?
