The only reason I suggest to use all the trick flow stuff is because the are made to work with each other. The pistons are custom made to match the heads and have the reliefs for the big vavles. I am running a 306 with tfs heads, pistons, and stage II cam. I have never had the car on a dyno, but by using the hp calulators it makes about 380hp. I have ran many different cams and the tfs cam made the most power. I have ran a fms f&x 303 cam and a custom ground one with alot of lift but the tfs mafe the most power because the numbers for the cam are made to match the heads. I havent use a tfs intake but they seem to be the hot ticket for a street/strip motor. I am using an edelbrock performer rpm intake right now.
