What’s the best rods for the build

Any H beam rod. Better metallurgy & uses a bigger bolt [ 7/16" ] v factory 3/8". And the H beams use bolt only, not nut & bolt. The greatest benefit over the factory rod is the factory has a cut in the shank to take the bolt head; that weakens it. H beams do not have this built-in weakness.

The 440Source "stock replacement" rods use 7/16" capscrews and are modeled after 426 Hemi rods. They currently have a clearance deal on "blem" RB rods, set of 8 for $150... description says balance was either slightly out of tolerance or small end was honed slightly too large for press-fit pins so they could be used with floating pins or have bronze bushings added.
