I just did the same mod back a couple of months ago.
Depending on age of lifters your probably don't need to replace. I didn't.
I did hte UD pulley. Might as well for all the bucko's you're spending and you have it off already.
Injectors can stay the same. mine are not showing to be pushing the duty cycle.
You might want to consider some tuning software.
I'm doing the numbers per my sig on a Mustang dyno. I think I can get another 20-25 rwhp of if her with tuning. If you run on a dynojet, figure that you will have about 15% higher numbers.

UD pulley, yes.
Lifters, depends on the mileage on your stock ones. If not high mileage I would save the money.
Injectors, yes you will be maxing out the stock ones.
You should make 450+whp.

Thanks Guys, Y'all have been very helpfull! 
On a HAPPY note, the vendor made contact with me today.
They are going to replace the FAST intake with a 90!
Even though I have shaved the LOGO's off of it, and done some paint work to it.
They said it was there mistake, so no problem!
I just wish I had realized it ws the wrong one from the start, so they would be getting it back same as stock. :o
Thanks again, God Speed, Doc....

I just finished up my h/c set up and went to start it up and with the heavier springs it instantly collapsed on of the lifters mine had 60k on them now i have to pull it all apart to put lifters in it. Stock lifters are a touch over 100 dollars. I just bought some clevite llifters and new lifter trays. just my .02
