not much at all with just heads, you might want to throw in a cam at the same time for maximum powere increase.

I would say with a port and polish, 15 hp. If you get some custom regrind cams also, easy 30rwhp.
I'm looking into this myslef.
Get an off road pipe and some steeda pullies if you want to go faster

I've got a BBK Offroad H pipe for sale. I took off my '01 GT 5 - speed. Make me an offer if you're interested.

I'd love to see someone put together a n/a 2V 4.6L with ported motorsport heads, intake & custom cam, etc. If you could get 300hp at the wheels, I'd probably go that route myself.

a dream of mine is to stroke my 2V, I wanna see what the best a N/A 2V can run. but that stuff costs a lot of money so that is why it is a DREAM.

Besides flows u don't have any performance mods 
. Like has already been suggested: pullies, intermediate pipe (o/r), gears, t/a or chip, hell, u could get a nitrous kit for what you're gonna pay in labor alone on the p/p .Go for the basic mods first 
.

Fastest N/A 2V with no internals is 12.89. A guy on the corral did it. There are a few guys running a SHM 300 stroker, and I know there in the low low 12's.
