bunches of questions!!!
bunches of questions!!! ok..some of you might know, what I have 00 Z28 140K miles A4 with 3.73's..blown motor and a sts rear mount on it...okay...pulling the motor and putting forged pistons in, more than likely wiseco's and maaaaybe different rods, not sure yet but anyways here we go...
6.0 heads..no brainer to get them?
---if I use those what dish/dome do I need for proper compression for FI?
---Head gaskets? thickness? the ls1 ones or the 6.0 ones?
Oil pump?
---Use stock one or go with an aftermarket? What do you guys suggest?
Timing Chain?
---New stock or other recommended?
Cam?
---Turbo cam? custom cam?
PCV system?
---Such a great question I know, the LS6 valley and go from there? or can use stock setup with a simple easy way?
MAF or delete and use 2-bar?
---the guy that is going to dyno tune says using the maf is a little more street friendly..what have you guys experienced? i'd like to do away with it
FUELING
Pump?
---been looking at TSP's plug and play for around 200 bucks...anyone use this? or is there a different route to be taken?
Injectors?
---tuner said to get siemens deka 4 60lb-ers..also said he wouldnt touch it until it had different injectors and a different fuel pump in it because he says the stock injectors are pretty well maxed out already......recommendations??
a couple years down the road i MIGHT go with a t76 of some sort so you can keep that in mind if you'd like..but would like to get this setup mastered first
If there is anything else I am missing or you would like to suggest please feel free to help.....please dont recommend the most EXPENSIVE options there are..as for I am NOT made of money but will do what has to be done...thank you so much in advance!

What kind of hp are you looking at? Any clue? I'm pretty sure 255lph pumps are only rated for about 500-550hp
Oil pump, you can use stock, there are a few threads with people using a stock on a turbo setup, I'd personally go with a ported LS6 or melling High Volume, not sure high pressure would be what you want in fears of blowing past the turbo seals.
Timing chain, I would think a stock would be fine, but if you wanted a little extra insurance maybe Cloyes sprockets and a C5R chain.
With the MAF can you use the MAF for idle and low rpm then have the PCM use the MAP sensor for speed density for the mid-upper rpm's? Not real sure about tuning, just a thought, may not be worth the bandwidth it used.

There is a couple ways to set up your PCV system, but this should help you out.
