Porting is a pain in the ass. Not that difficult (exhaust mani, o2 housings, etc.) but is very time consuming. I have ported a little bit but always get too tired to finish the job. The tools you need are a die grinder and bits. That is it. Different size bits for different jobs. Get good tool though. They will help you alot. I have used a die grinder (pnumatic) and a dremel (electric). Both work ok but there are probly better tools for the job.
