Dude! do a search. I did my heads. I found link on here somewhere that brought me to a site for crossfire corvettes. There was an excellent article complete with pics. Get a porting kit from Standard abrasives-Summit sells these, about $40. It has instructions in the box on head porting as well. You will need a phnumatic (phnumatic?) die grinder and a good quality carbide bit. Get a big one shaped like an oval. MAKE SURE IT IS A SINGLE CUT BIT !!!! For aluminum you cannot use a double cut as it loads up to fast. Take your time and be patient. Horsepower will be your reward.
