Are you set on using Scat parts? If not, I might suggest as has @PROSTOCKTOM , Molnar parts. In my 408 built in 2015, K1 was used, these are top shelf parts. Scat I beam rods with Chevy Journals, and Diamond piston. A quick look around and it seems these parts might be available, plus it gives you a lighter wrist pin. As @pittsburghracer stated, collect your parts yourself and bring to a competent shop. You save the markup this way also.
