By purchasing a Stage One engine kit, your engine head will be ported and polished to help you achieve maximum horsepower by allowing the proper amount of air into your engine. The process is completed with a precision valve job to seal in all the combustion pressure.
You will need to send in your head with this kit, so we can perform the port and polish.
