Best piston choice for build

[Thor06]

How much does it take to get the 1g big rods machined out to fit on 2g pistons? I'm in the same spot, if its going to cost alot, I think I am going to go with a 1g big rod and wiseco setup. I dont have that much money so I dont think I will be getting any Eagle rods, but some o/s pistons with new rings, straight cylinders, and higher compression would be nice.
