ported heads

  1. Built heads?

    Built Motor Discussion
    I have a 06 sti and am building the motor with forged internals and a ets rotated kit, 6266 precision turbo. I am thinking about building the heads, port and polish, bc cams and maybe 1 over valves but am not sure if it will be worth it. Are there any real advantages to those mods for my power...
