Setup Suggestions, input greatly appreciated!

[Constant_Project21]

I'm in the process of planning out my new setup for my 1g. I've decieded to go a little more built than first expected, and would greatly appreciate input. I've talked this over with Bob at work (MAP porting guru) but never hurts to ask for more opinions. Here's what I have planned, for the new setup, but also have some unknowns that still need to filled in- (btw, my goal will ultimately be a pretty reliable 400hp car on e85 eventually, maybe not until I upgrade the snail)

Basic engine:
MAP stage 1 shortblock, with the BSE kit, stock crank, just their basic build, with a few exceptions.

RODS-eagle, the ones that come with all stage one builds. I've been told they should have no problem handling 600hp

PISTONS-wiesco, and this is one spot I would like input on. The stage one build comes with the option of an 8.3:1 Manley, or a 8.5:1 wiesco. After chatting with Bob, he had suggested going with a higher compression ratio, something like a 8.8:1, 9:1, or even a 9.5:1, due to my 16g/e85 combo. He said, that I would benifit from the extra compression on the smaller turbo and on corn juice. (the planned successor to the 16g, would be a fp3052 or something similar, keep that in mind) What are your thoughts, and what compression ratio would you recommend going with?

HEAD(1g): There will be some mild port/polish work done, as well as a valve job and some cleaning of the bowls. I discussed a possible 1mm oversized
valves, but overall don't think I would benifit too much from it, so believe I will be sticking with stock valves (chime in if you have suggestions relating to valves). Springs/retainers, may see an upgrade, but then again, a 16g doesn't have the craziest top end, and won't be revving to the moon.

CAMS: The car used to have hks264's, which have been sold. I don't want to throw a ton of money at cams, so those of you using a cheaper yet effective cam, please share some insight on some possible suggestions.

TURBO: A ported, externally gated 16g (for now). I have one, which is why I'm going that route, and as mentioned before, plan to go bigger down the road.

FUEL SYSTEM: This is the biggest unknown for me. I currently have a walbro 255hp, on a stock fpr. I recently aquired FIC (Bosch) 1600cc injectors (overkill, but no need to upgrade), so those will be my injectors. My question is, is there any reason to use anything more than the one 255? I've been told in the past I may need a second pump, but recently have been told otherwise. I'll be putting a AFPR on as well.

EXHAUST: Have a full 3" N1 already, and will be using a MAP recirc o2 housing, paired with a tial mvs wastegate. Plan to pick up an Fp race manifold as well.

TUNING: DSMlink

Any input will be helpful. May have left a few things out, typing this on my iPhone, because my computer is being dumb, and couldve left some things out.

Thanks in advance!!
