  6. WIldcat 240 Valve Springs & Retainers
The Wildcat 240RS has a WC946 Non-Hemi Head with 26-lb springs and billet aluminum retainers. We have replacement retainers and springs for the Wildcat 240 and dual springs and titanium retainers for those who want to modify and upgrade their cylinder heads. Spring pockets will need to be cut for dual valve springs, and longer valves may be required to get the ideal install height to support higher spring pressures and valve lift. 

Always check your coil bind and retainer-to-valve guide clearance. Getting into higher lift ranges without checking coil bind or retainer-to-valve guide clearance is one of the most common reasons for valve train failure. You should have more than .060 before the coil bind and more than .050 between the bottom of the retainer and the top of the valve guide.
