TFS heads and intakes are good stuff. Just installed 331 in my stang with all stuff listed in my sig...having said that I am still breaking in the motor but i can tell you she wants to GO BABY GO. E cam doesn't pick up too much power below 3000 and I haven't taken her too much past that.
I wouldn't run anything less than 24 lbers with a TFS kit. New injectors=new MAF too. Since the motor is torn down new lifters would be a good idea. Headers...if the ones you have now are in good condition I wouldn't get new ones and yes most def a 255 fuel pump. Would go with a bigger throttle body too. Doesn't it suck when all you want is more power but every part needs to compliment one another.
