friend of mine bought some trickflow heads and cams, his old cam gears are press on, hes wondering if he has the, pressed off can he put them on his new cams with the supplied hardware? or does he need to get adjustable cam gears?

 

You need to use the bolt on cam gears. You can use stock gears, but you can't use the press on style. Romeo heads have the bolt on style, and Trickflow does sell them, with hardware, as a kit. You can also probably grab a set at your local auto parts store through Cloyes. If going the latter route, make sure you specify a car, as the press-on Windsor styles were mainly put on trucks.
