There are alot of different stuff out there And I think alot of ppl use Edelbrock stuff you can get everything from Carbs, Intakes, Cams, Heads. The Performer line and Performer RPM line are Designed to work together.
For headers I like Thorleys some members have used Flow tech, Headman, and Hookers.

If you're going to put 35s on it, you will best served to spend $$$ on a rear end/front end gear change.

Call a reputable cam manuf. (crane, comp, etc) and tell them your current gear ratio, tire size, power desires. They will help you decide on the rest.
