    Wow, thanks! Not sure why I only got notified of your reply just now, must be my settings.
    I've looked at buyee and other similar proxies but this one seems to be the most trouble-free, will give them a shot.

    more to come......
    So, I need to make a small correction. .408" is not the valve lift of the new cam, the "new" cam is closer to .440" valve lift lift (original valve lift was .350"). Seat pressure doesn't change, just the pressure on the nose. My engine builder recommended about 100# seat pressures and about 220#s on the nose.

    I began my search with SBI and their spring info charts: http://www.sbi-e-catalog.com/Specification.aspx (pulldown menu - select valve springs) we couldn't find the perfect fit..... close but wound* the incorrect way.

    * - as my engine/head experience is almost entirely utilizing single springs.... I didn't know that dual springs are wound opposite directions (inner versus outer) This allows the springs to bypass each other - even if there is a slight interference fit - if they were wond in the same direction one spring could interfere with the other.




    After spending a few hours looking, and comparing, and not finding what I needed I called PAC Racing - they make valve springs for MANY different application. I sent them the specs I needed, and they got back in touch with me.... they DID have a spring that fit my requiremeents, the only problem was it was a proprietary inner spring for AFR. Matt, the PAC Spring rep, asked AFR if they would sell me 16, AFR agreed......



    seat pressure: 50#, pressure @ .440" lift: 85#, coil bind @ .585" lift.
