Welcome to the forums!
The steps are usually (in order of ease & cost) intake, exhaust, cam, head. So start with the filter, carby & manifold, extractors & exhaust system before you start opening her up.
Also what car is it in, and more importantly what has the motor got now? Where are you located, might help people direct you to local sources of parts/info/help.
