Default engine ideas??

well guys i blew my head gasket on my 1990 last thursday and the engine needs quite a bit of work anyway so im tryin to get my hands on another engine to build and swap into the truck... the engine is out of a 92 that im tryin to get. im gonna tear it down and re ring it and all new gaskets bearings and a pump rebuild before i swap it in. now my question is what do yall think i should to to it performance wise? my current engine has p.o.d sticks, the pump is cranked pretty good, 16 exhaust housing on the turbo, and i got a airdog 100 and it ran good enough to put down 289hp and 500tq on the dyno but i want more for this next engine so what do yall think? what injectors should i run? fuel pin? i got a hx35 i could put on off of a 24 valve and i have a airesearch m.10 i could use for twins. i want a solid 350 or maayyybeeee 400 horse but what do i need to get there? any help is greatly appreciated

well

Studs
Gauges
SDX 140HP injectors
Denny T pin or AFC delete (if its not a DD)
Good clutch or built auto
max out your pump internally not just with the FP screw
ditch the H1C and get a nice turbo l
the AirDog 100 will be enough
20 over head gasket
60lb springs for I&E
4200 Governor spring

theres a start

Cummins 12V 89-93
