Valve Spring Clearance. the installed height is defined as the distance from the spring seat in the head to the bottom of the valve spring retainer. valve clearance, or tappet clearance, is the gap between the tip of the valve and the rocker arm when a solid lifter is positioned. The ends of the spring are ground flat to sit flush on. check the retainer to valve guide clearance (allow room for the valve seal if it isn’t installed when taking your measurement). the basic valve spring is a single wire, cylinder shaped spring. to check if the spring has sufficient coil bind clearance use the valve spring installed height on the seat, minus cam lobe lift, multiplied by rocker arm ratio, plus valve lash, minus the safety margin. At full valve lift, your valve springs should have, at the very least,.050” of clearance between the coil. Also, make sure that there is sufficient clearance between the spring retainer and rocker arm.
