MFR Small Block Chevy 198cc Aluminum Cylinder Heads

MFR Small Block Chevy 198cc Aluminum Cylinder Heads


MFR SB Chevy  heads come in a 198cc Intake runner with 2.02″/1.6″ valves, 64cc combustion chambers and straight plugs for better header clearance. In stock and ready to ship. Stainless Steel Valves, Comp Cams, Manley or Pac Springs, 10° locks, retainers, 3/8 or 7/16 studs and 5/16 guide plates are included. I have used these heads and found to be of the utmost quality castings and machining available. These are not ProComp or Speedmaster.
