Ok I am wanting to put these gt40 heads and intake on my car. I have a 75mm throttle body
And spacer. Also thinking ab buying new fuel rails with 24 lb injectors. And 75mm MAF housing with sensor. Will I have to do anything to this computer?

Unless you're going to supercharge or turbo the motor, the injectors and tb are wayyyy over kill. Your stock 19lb injectors are good for 300-350 hp set up. With the heads and intake, you won't be anywhere near 300. Also, 65mm tb is more than enough too.
I have a 91 vert 5.0, and I'm rockin gt40 heads and intake, e303 cam, 65mm tb, cai, shorty bbk headers, bbk x w/highflow cats, and slp lm1 cat backs. I haven't dyno'd the car but I know the setup is still sub 300hp.

Well that's a bumer done bought the parts lol
What else can I do to pick up more power ?
Don't money for turbo or super charge nor
The how to lol. Car has under drive pulleys
Headers x pipe with flows msd coil. Racing
Fuel pump. After I get these heads an intake
On I'm goin to put 3.73 gears in it. ???
Also which would be easier on labor turbo
Or super charger? And cheaper to do?

I'd do the gears first as that's by far the best bang for the buck you can do for these cars. Then decide on what you want out of your car, daily driver, track only, etc etc. Then set a limit on funds, and start researching pros and cons of the mods your looking at.
Use the search feature here and you'll be reading for days.

I would skip the porting work on the GT40s unless you can do it yourself. Its just not a very good financial investment. I say that as a guy that had his ported and put on the flow bench. Run the springs your cam recommends.
Like '88 said, figure out what you want to do with the car. Some of the best money I've spent on mine, as just a fun street car on a budget, is FRPP B springs. If I was going to drag all the time I'd probably have went with stock 4 cylinder springs. BOTH are cheap options.

Yeah, 373 gears will make a big differance on the ol' butt dyno. Makes the car really wake up. The last few guys that posted really had good advice. Its all about what you want to do with your ride.
I will say, with the tb, injectors, and fuel pump you have, I'd save the dough for a twisted wedge hci package. If memory serves me correct, the "street burner" package is good for 350+ish hp. Maybe look into that.
