Brand-new GM castings form the basis of the PRC cylinder head lineup including the L92/LS3 ported cylinder heads. PRC takes them through a full five-axis CNC program that results in increases to both intake and exhaust flow. In the base PRC configuration, the heads sell for $1,199.99 under PN 199-L92.
