Just how much?
Everything is additive, it can't flow into the engine any better till you let it flow out just as easliy. With those mods you would see more gains from a header install than if it were done to a stock intake.

you'd probably see around 12rwhp at most.... but like said supporting mods will help it breath more and up the induction numbers with exhaust

Someone with longtubes headers upgrading to a better lid and all that might see 15 hp... whereas someone without may only see 6 or so. They all build on eachother... induction and exhaust parts that is.
I did my full exhaust first because I wanted that rip your face off sound and it was the more expensive part... and now that I dont want to have to spend that kind of money right now.. 100$ for a lid and 10$ for the things you need for the throttle body seems like a steal for mods.
You might also consider a smooth bellows (fernco 3"x3" rubber coupling) and perhaps fabbing up a better ram air... like the custom grille ram air that people are seeing good results with for like 15$.
Get a stall,full exhaust, p&p tb and bump stop mod and nittos you're in mid-high 12s.
I'm a stall away for mid -high 12s.
