2350 isx rebuild recommendations

[Gonefishin900]

My isx has liner orings leaking on #2. Motor has 1.3m km on it with what I believe is original crank cam, head, turbo ect. I will be rebuilding myself, hiring the counter bores out.
I did some reading on opinions on aftermarket kits which aren’t a fan favorite on here. The truck will see like 20-30k km a year so I cannot justify the exponentially higher cost of Cummins parts. I’ve used {garbage aftermarket} kits in past builds…. Is there kits that come with everything I need? Quality wise one better than the other?
I want to replace
Head
Liner packs
Bearings
Oil pump
Oil cooler(truck had high oil temps prior) or change the thermostat??
Water pump/thermostat
Turbo…. Is original. I don’t want to spend the 10k on a new one from Cummins. And I see straight vane turbos have poor reviews here. I could care less if I lose some Jake power. Options!?
Vibration damper
Trucks deleted and I’d like to remove the egr cooler and put a bypass pipe in. While it’s apart an before it starts to leak.

Is there anything else I should be changing?
Thanks
