Default Currently FP green on e85, debating fp red

Soooo long story short, I got about 3k miles on this set up and made 530whp/550tq on e85 (actual e70). Then I blew head gaskets on both sides. Not quite sure what happened but turned into a complete tear down of IAG stage 2.5 block. Bearings showed abnormal wear blah blah blah. Not important.

I kinda want to hit the 600whp club. But this was a purpose built street car. I wanted boost to kick in asap, and I did everything I could to make that happen.

So I'm thinking about going with a FP Red to get me there as the green is maxed out for sure.

Current build:
IAG Stage 2.5 Closed Deck
B25 heads - Full PnP, GSC S2 272 Cams, GSC STD Valves, GSC P-D Dual Springs, Titanium Retainers, Bronze Guides -
ARP 625+ HeadStuds
OEM Headgaskets
12mm JDM Oil Pump
JDM Hi-Flow 2 Port Water Pump
Oil Heater Delete
Killer B Ultimate Oil Pan, Baffle & Pick Up
Haltech Elite 2500 ECU with Boomslang Harness
Haltech Canbus Wideband Controller
Haltech 12 I/O Expander
Flexfuel/Speed Density

Bolt Ons:
FP Green HTZ Turbine Coated with 84mm Inlet
Torque Solutions AVCS/Turbo SS Braided Oil Feed Line
Id1700x Injectors
Outfront Rails with Socketless -6AN Lines
Turbosmart FPR /wAEM Fuel Pressure Sensor
Fuel Labs 6 Micro Filter
DW400 Fuel Pump Hardwired
NGK Iridium IX 1 Step Colder .022-.024 Gap LFR7AIX
Killer B Holy Headers Swaintech Coated 38mm Tial MV-S Wastegate (17.40 PSI Black, Blue)
IAG v2 TGV Deletes with 19MM KSTech Phenolic Spacers
IAG V3 Street AOS
COBB 4 Bar MAP
Chevy OEM 3 Port EBCS
Treadstone 600hp FMIC /w Reverse Intake Manifold
Rife IAT Sensor
SYLTECH - 1/8***8243; MSCS Pressure Temp Combo Sensor
Tial Q BOV 11lb spring
Getadom Cyl 4 Cooling Mod
Cobb CAI system
Cobb Catless 3" Stainless Turbo Back
Mishimoto Radiator
Evil Energy Coolant Reservoir
Aluminati Coolant Expansion Tank
MOTUL Synergie 10w-40
Subaru Blue Super Coolant


Now, everything is going to remain the same except the following:
Pinned mains, ARP case/main bolts (so deck will be shaved a bit)
Shaved heads (just a little)
IAG Cooper Ring Head Gaskets (.051" thickness vs .058" OEM)
GSC +1 Intake Valves, GSC +1 Super Alloy Valves
FluidAmpr 531101 Crank Pulley

So my compression is going to get a bump and my airflow is going to get a bit of a bump due to bigger Valves.

Now, I think FP red will get me to 600whp. But my worry is how high my power band will move. As the purpose is a street car.... if it moves too high, then I'm going to stick with fp green and say oh well. I just don't think I can get anymore power out of the fp green.

Opinions?
