New CPL# for rebuild

[NoTime]

I’m in process of rebuilding 2013 2350 due to carbon packing. The original engine number is 79672960 450hp. I want to rebuild it to a 79646458 which is a 600hp. Looking thru quickserve part numbers it looks like the piston and liners, cam, and injectors are the same but the head and turbo are different. I can understand the turbo being different but what’s up with the head being different?

I’ll take some picks if the intake side of the head for you guys. You literally can just barely make out the valve stems from the packed in carbon at 583,000. I don’t know how it was running. Lol

Yes replacing trans with a rebuilt 2050 18 speed. Just hope rear ends make it a while. Lol
