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,

i always like a question or too about the leaning tower of power/ blue buzzin half dozen. your teachers were right except try more like up of 500hp if done right i have seem dual four barrel intakes (as well as single offy makes a goods one). so i would advise a single 4bbl intake with 600 edelbrock 280/484 camcraft cam 10.5-1 compression piston, nice head port job/matching intake bigger valves minor ect msd ect. that will make 300+ easy + streetable with a little lump
