    Need 350x valve specs

    I am out of town and have not torn the 350x motor I have down yet. But I need the following is you could help out. This would benefit all 350x owners to be honest.

    Intake and exhaust separately.
    Stem diameter
    Length of valve overall
    Seat diameter
    And if possible distance of retainer grove from tip

    Thanks a ton. I am working on a possible solution to lack of performance valves out there for stock rebuilds that will be so much better than stock style.

    Here is the info from the Vesrah site:
    Click image for larger version.

    It doesn't list the retainer groove to tip distance though... I can measure my valves when I get home tonight if you don't get the info sooner.

    Crap!!! Company said they had nothing that for those sizes. So it would be custom. $28 per valve with a 50 minimum of each size. So basically 25 350x sets of performance valves.
