    are you asking for larger valves or just wanting to replace the valves that are in the heads already? and why do you want to replace them?

    valves

    im wanting to replace them with better valves so i dont run into the chance of breaking the stock ones plus i was told that the cam is too big for the stock valves. im just looking for something that is going to work and allow the power i want. plus im in iraq and i cant really run around and find this stuff, i gotta find it and send it to my mechanic.
