Rod length is, basically, irrelevant.

As far as the CHP kits...the reason I did that (originally) was because the only 5.956 rod that was available was stock. Using the 6.200 allowed a decent piston and a lot of options for upgrading the rod.

Probably the best reason for using it now is the comparative weights of the 1.350 C/H piston and the 1.600 C/H piston.

If you already have the crank and rods....changing the piston is probably the way to go if you wish to save money.

It's what I'd do. You can always build a different short block for the future, especially since the heads will outperform the combination.
