Cut for Dual Springs - Per Head

With higher lift cams and larger valves, you need more seat pressure. That means dual springs!
$60.00

In order to control your valves and prevent float at higher RPMs with performance cams and larger/heavier vlaves you need to upgrade to dual springs.  In order to make those dual springs fit, the vlave pocket must be cut so the inner spring will fit over the guide boss.
