    Default Supertech Engine Valves.

    Hi all,

    Real time Feed back is required on the performance of the Supertech valves used in a 16 valve 4age in the Standard size using factory original valve seats.

    I have had first hand reports of the stainless supertech and Ferrara inlet valves "galling" and are uncompatiable with the orginal factory valve seats in the 20 valve engines,with valve clearances closing up after only a few hours track time.The problem is overcome by insalling new valve seats.

    I've used them a few times, only time I've ever seen them have problems was people hand-lapping their own valves in instead of getting the seats cut properly in the first place.

    Same deal with 16v, no issues at all.

    Supertech stuff comes highly recommended from some older mechanics I know.
