What I learned

had a set of E7TE heads, ported, polished, 1.94/1.50 valves installed, chambers modded, etc. They just barely out flowed a set of untouched World Products Windsor JR's, spent over 1200 dolllars for this.

Got a set of AFR 185's on my new motor. They spank those ported E7TE's so bad it aint even worth making a joke about and you can get them for about 1400 a set.

Dont mess around with stockers unless you into some kinda fetish.

I disagree, I believe that stock heads can be made to flow very well. Look how well Thumper heads work.
It all depends on the rest of the your set that you plan.
The key to heads is flow velocity . Bigger is not always better. If you install 1.94/60 valves with a competition 5 angle valve job with porting & polishing and port match the gasket, those heads will flow well.
Then what you want is a cam that produces lots of low-mid range power, and a good intake & exhaust system.
Remember, you want flow velocity so that's why you keep to a mild cam. BTW, I think those 30# injectors will be too much. I would go witth 24# injectors instead.
Now, if you're looking for 6000+ shift points and plan on building a strip only car then by all means go with aftermarket heads.
If you want a good street car, low end torque is what you want.
BTW, 88 workcar , is running 11's with stock E7 heads with no power adders!
