    z20let head

    Does anyone know if the zlet head is the same as the non turbo models ??like the x20xev, also are the valves the same.
    I need to swap the head as ive just noticed the previous owner has snapped 1 exhaust stud in it and over tightend another which has also damaged the head.
    I was thinking as i need a new head i might aswell get it ported and get bigger valves fitted.
