ProComp/Speedmaster aluminum heads

Here's or maybe I can get somebody to step into this conversation with a little bit of reality for 318 has valves that will fly...?
Once you start getting a 3000 lb approximately brick going down a straight away the difference between getting a car to go from 15 seconds down to 13 seconds is 10 times easier than trying to get a car to go from 12 seconds down to 10....
CAN I GET SOME HELP HERE..??
I take this you don't want my contest? I'll start the thread if you'd like? No confidence in those aluminum heads? Or scared of my heads? :D :D
