Need Head Help?

Two of my teachers in high school ranted and raved about 225/6 pushing 300+ hp. i have a short block that came with my barracuda with .30 pistons. how can i make this baby push 300+ i also have headers and a 4bbl intake that may be worth more than the car was paid for... this said any suggestions?

thank you for offering your services hard to find anyone who will give advice that isnt making a buck off of it and when profitability comes into play it can be hard to trust said advice...

thanks,
