Advice needed on used crate engine

My block had the stamped steel rockers like yours does and mine had the KB Performance Silv-O-Lite hypereutectic pistons. I called KB and they verified the pistons were special made for Mopar crate motor program.

I used the block and heads to build my 408 stroker for my Demon. But, I still have the pistons, rods, crank, balancer, oil pan, and M1 intake if you want to turn your's into a "Super Commando".

Heres some pics of the head numbers and the pistons and rods.
