Reaper EVO 574 cam requires performance valve springs, like Feuling 566032, 707562 or 566034. Performance lifters recommended but not required. Will work with factory pushrods on engines with factory height, if deck height, cylinders or rocker boxes have been modified from stock then adjustable pushrods are required, as Feuling 566073, 566070 or 707315. Compatible with a stock engine but increased compression, cylinder head work and performance exhaust will make this cam come alive. Increased compression is required for bottom end performance.
