SVE Performance CNC Cylinder Heads - 185CC Increase horsepower and torque in your 1993-1995 F-150 SVT Lightning 5.8 with SVE CNC 185cc aluminum cylinder heads. SVE aluminum cylinder heads are the perfect upgrade for your Lightning. Enlarged ports and valves provide more airflow for increased power, while the aluminum construction reduces weight compared to stock cast iron heads. The fully CNC 185cc intake ports allow for 289.16 CFM max airflow at 0.60" lift and a 58cc combustion chamber size. SVE's 185cc heads undergo a CNC machining process that cleans up any flaws the "as cast" heads may have, which further increases airflow and performance. SVE heads come fully assembled with 3/8" rockers studs, upgraded hydraulic roller dual valve springs, Viton valve seals, guide plates, machined bead valve locks, hardened spring cups, Manley steel retainers, and one-piece 8mm valves. Intake valves measure in at 2.02", and exhaust valves measure 1.60" big enough to flow all the air your Windsor engine would need. These stud mount heads are fully assembled and are finished off with a 3-angle valve job meaning that you will be able to bolt the cylinder heads to your short block for an effortless upgrade!
