Help me on my engine build!

When i bought my truck the owner said it was rebuilt and had a Lunati Voodoo cam. I have NO idea which it is or a part number. It also has a MSD ignition, shortys and that looks to be it as far as aftermarket is concerned
I want to bump it up some. I was debating having it .30 over but i dont want to go that far into it. I would like some new heads, a aggressive cam, new exhaust, new fuel delivery system and new upper and lower intakes.
I am just confused and dont know what will work with a stock block and stock pistons as far as heads are concerned.

---Upper and lower intake will be the edelbrock permormer truck intake (#3881) WITH a 1.0" heat spacer from trickflow(TFS-51520009)
---New fuel rails (on summit-#PFS-10601)
What heads do i use with stock bore and stock pistons? I dont want gt40 heads. I know they are a good upgrade but i want to go for a new set.
What cam do i use to compliment the heads?
Do i have to change the injectors to like 24lb/hr or bigger?
Do i need a bigger fuel pump? etc etc

all help is sooo very appreciated!
Is the exhaust stock besides the headers?
Do you have a budget for EFI and fuel system upgrades?
Aftermarket heads and intake that require larger injectors will also require a MAF conversion with a tuner and fuel system upgrades, you can't just throw in larger injectors and fuel pump and expect the stock EFI system to work correctly.
The exhaust is shortys into a y pipe that leads into a 2 1/2 pipe and cuts off right after the cab. no exhaust, no cats
I do have a budget of about 5,000.
Ill try to read up on the MAF conversion so I dont ask tomany stupid questions, but how much would a tune cost?
Thus being said, is there a specific heads i could use that utilizes stock bore, stock pistons and still pair up to the edelbrock performer intake? Id like to use RR to, 1.6?
