Saw your other post about the heads. You need to get your sh!+ together soldier and factor in all the other things like transmission, rear end gears, tire size, torque converter if it's automatic, and remember that the cam and heads have to match up with all the rest of the car and the way you are planning on using it. Take all that to the cam manufacturers and they should have a recommendation as to the head and cam combo that will work best. Your stock headers will be a choke point as will the stock intake parts. You should investigate whether you will need a bigger mass air meter, injectors, fuel pressure regulator and fuel pump. Or just say the hell with it and throw a 750 holley on it and sell the fuel injection stuff to finance the heads, cam and headers.
