save up for heads so you can get the gains from the cam you just spent your money on. when you pull the intake off you are pretty much already there for the head swap.
for a DD seing strip duty on weekends I would vote gt40 heads and intake. its a sick combo that will pull well over 5k rpms and gives up very little low end torque.
If its a full blown track car track heat would be better.
I have the trickflow head and stage 1 cam and a gt-40 tube intake and love it. i know i gave up a few ponies but i Found a NOS gt40 intake and i love the looks of it. It runs very well for not haveing a trick flow intake to. so just my 2cents
If you can afford the tfs intake I'd go with it, but your heads are going to be your downfall for either intake, doesnt really matter which you chose, both are good intakes.
