SVE Performance Cylinder Heads - 170cc
Increase horsepower and torque in your 1979-1995 Mustang 5.0 or 5.8 with SVE performance 170cc aluminum cylinder heads. SVE aluminum cylinder heads are the perfect upgrade for your Fox Body or SN-95. Enlarged ports and valves provide more airflow for increased power, while the aluminum construction reduces weight compared to stock cast iron heads. The 170cc intake ports allow for 263 CFM max airflow at 0.60" lift and a 56cc combustion chamber size. SVE heads come fully assembled with 3/8" rockers studs, upgraded hydraulic roller valve springs, Viton valve seals, guide plates, machined bead valve locks, hardened spring cups, Manley steel retainers, and one-piece 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!
