Trickflow Ultra 18 Cylinder Heads, SB Chevy, 250cc Intake, Bare
TFS-3181B001-C01
Take the 18 degree power leap! Ideal for drag and high-rpm circle track racing, Trick Flow® Ultra 18® 250 cylinder heads make serious horsepower right out of the box. In fact, the heads deliver higher airflow numbers than fully prepped 23 degree small block Chevy heads.
These heads feature Trick Flow CNC-profiled combustion chambers and CNC Competition Ported runners with a premium high resolution surface finish for maximum flow and performance. The heads accept most current 18 degree intake manifolds, headers, and other components. They require the use of offset shaft-mounted rocker arms and a mechanical roller camshaft with offset intake lifters. Trick Flow® Ultra 18® cylinder heads are available fully assembled or as bare castings and sold individually.
