MoFlow-1 by BlackMarkit

The new Moflow has been completely reworked to accept "bigger" valves, utilizing a 36mm intake valve and a 27mm exhaust. The valve spacing has been widened to safely accommodate the larger valves, along with the rocker stands to keep everything lined up. The intake bolts have been changed from the 43mm spacing to a wider 46mm spacing to allow for the bigger port. Material is added on the spark plug side head bolts to move the bolt pattern if needed for larger bores. Long 3.100" stainless valves with Comp Cams GP965 springs and titanium retainers. Must use billet valve cover or valve cover spacer for clearance. Must use Blackmarkit intake or modify intake for 46mm spacing. Recommend 1/4" x 5.5" pushrods (length may vary, depending on rockers). Designed to be used with Gage Motorsports Black Venom rocker arms.
