MRF Small Block Ford 185cc Aluminum Cylinder Heads

MRF Small Block Ford 185cc Aluminum Cylinder Heads


MFR SB Ford heads come in a 185cc Intake runner with 2.02 intake and 1.6″ 8 mm valves with 60cc combustion chambers. They are 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.
