    I think you need to measure from the spring seat to top of valve guide, with valve and seal removed of course.

    To measure how much height between before your retainer hits the valve seal, you measure the distanced between the bottom of the retainer/locks and the top of the valve seal, then remember you can't actually touch the valve seal with the retainer/locks or it's game over for sealing.

    Keep in mind that springs have a bind height to consider, also that our heads with modded retainers etc only give us approximately 1.78x" (spring seat to retainer). Almost every aftermarket spring we install expects 1.800". That bit of less space is adding preload and also takes away from your bind height number because you'll automatically be less that amount.

    Plus different locks make the various retainers sit differently http://s20.photobucket.com/user/bill...ures/Retainers

    I drink..so consider that when reading my posts.
