I have the MS3 cam (237/242 .603 .609 112 LSA), hardened 7.40 pushrods, CNC ported LS6 heads with 64cc chambers, and forged pistons with -2cc valve reliefs. I just had my heads milled to 60cc chambers. Will I need to change anything with my rockers or pushrods? How do I check?

You don't mention which rockers, but I assume stock. The following link is how I set up my Yella Terras. For stock, method is the same but you must shim under the aluminum support that sits under the rockers to adjust the wipe pattern. Note that pushrod length will not change the wipe pattern, only the rocker height adjustment will do this on a non-adjustable rocker. Once you get the wipe pattern correct, then measure for pushrods. Note that any shimming required will change the pushrod length to get the proper lifter preload.
