    Ya a port and polish is a great idea, you could do it yourself if you have the port and polish kit and a good eye, or you could send it off to a machine shop..

    Kibblewhite springs and valves are a good idea if you are using a hardfaced cam

    but i here if you are using any hotcam you can use stock valves and springs (that is if yours are in good condition )

    It all really depends on what your motor set up is going to be

    thats what i was thinking, so i can use the stock valve springs and valves with a stg 2? also if i buy a stage two without the chain gear on it, is the stock gear interchangeable?
