Small block cylinder head question

OK,, Ive learned a few things through this thread so far today. Ive verified my intake as being an edelbrock victor. So far the 2 heads that were said to be a better pickup is the promaxx or a set of edelbrock heads. No one actually said there would be a good gain with the x heads.
Then, and probably more important I found that Ive painted my car the wrong color as Ive gone white with blue stripes and both the red and yellow cars are faster with yellow (per Google) being the fastest! lol
As for how I plan on using the car it will be mostly a street driven car. But I hope to race it a few times a year.
Thanks for everyones help.
