    4 Tec supertech inner valve springs won't fit over valve stem seal

    Sorry to bother you guys but i bought supertech valve springs and lightened valves but the Inner spring on the supertech set binds on the bottom of the valve seal and does not seat properly i have a 2012 rxp is there a fix or am i doing something wrong ? ,
    I have a Lez Cooke C kit 8800 rpm ecu with 629 cam and ported head should i just use the standard springs with Lez retainers and supertech lightened valves that a already have please ?,
    cheers ,

    The kit listed in the link is known to bind. Supertech now offers a spring/retainer combo specifically for the 4tech motor

    New part numbers:

    SPRK-EC3025/SE - 85lb seat pressure
    SPRK-EC3027/SE - 103lb seat pressure

    Thanks very much Scott ,
    I will have to contact Jerry and see about returning them and obtaining the correct ones,
    I just use the standard springs with the lightened valves and Lez Cooke retainers for the moment,
    Just as well i bought the Riva valve comp tool :],
    cheers mate ,
