Help with 451 piston choice please.

Hello,

I have been researching what pistons to go with for my 451 build, and have narrowed it down to the following. All of the KB's will require quench dome measuring and milling to some extent. Any suggestions on other piston options would be greatly appreciated. I am trying to find the best set of pistons that I can for around the five hundred dollar range. My block will clean/finish bore at .060" overbore.

Keith Black hypereutectic KB 215 or KB 251, with 6.358 400 rods.
Keith Black hypereutectic KB 280 with 6.768 440 rods.
Icon forged IC 823 or IC 837, with 6.768 440 rods.

Thanks
