Build Reccomendations 600+HP

First off,

Pickup is a 2008 6.7 2500

I smoked the stock trans in this truck about 7 months ago playing around in my hot tune. After going back and forth with myself, devils advocate prevailed. Knowing that the time would come where I wanted to build more HP, I decided upon a Revmax Signature Series 700

Truck is tuned through PPEI and Deleted, FASS 150 series, stock motor top to bottom, 5" exhaust to the back. I put the FASS on sometime ago due to my concerns with fuel quality in my rural area.

With the transmission in there, at this point I have taken care of one of the most costly upfront component prior to pushing more fuel through this machine

I've got a shopping-list that I wanted some input on,

Top End:
-58 LPM Dragon Flow Injectors from T&C Diesel Performance (accompanied by a Stroked Pump from T&C as well)
-ARP 625 Head Studs
-Stock Cummins Head Gasket
-103 Valve Springs and Tool Steel Retainers from Hamilton
-Hamilton Heavy Duty Push Rods
-XDP Fuel Canister Delete (My FASS system with CAT filters are more than adequate)

This is where I'm at a loss, I'd like to stick with a VGT turbo but I question that with a Upgraded VGT set-up will it hold me back when I want to pour the fuel? but still have street drive-ability.

I'm not interested in a compound set-up as I don't feel that's necessary to get me to where I'd like to build to (650-700HP) and I'm not interested in doing the tedious fabrication to do that.

I'd like to get this figured out soon so I can get this head pulled and checked and decked if need be. Then proceed with getting the rest of my components ordered.

I could use some direction and suggestions on the turbo set-up, as for the rest of my list, It's pretty cookie cutter for adding some strength to the Top End. Throw some suggestions down on your set-ups and your likes/dis-likes about them.

The VGT is the 1st thing I would not put back on one of these engines. An S464-S467 with an inline exh brake if you are going to tow with it for the HP #s you want. Your stock injectors will have you pretty much there under 600 but will be stretched out. New larger BBIs will certainly get you there.

2011,4wd LB/CC 2500 H&S Mini MCC by Tomeygun, BD protect 68rfe VB seperator plate enhanced stall triple disk TC, Super B 64.5/80/.91 3rd gen mani & inline EB, Arp 425s, Fass Titanium 95. Spare Mini in my closet.High tech old school and finally lovin it.

I would get injectors and pump from S&S. Injector size Id go with 100%s and have them pulled back. Turbo like said Id go with most likely a S464-S467 range.
