Trick Flow High Port Sbf 225cc Aluminum Bare Cylinder Head Castings 70cc

Serious CNC-ported horsepower! Trick Flow® High Port® 225 cylinder heads are specifically designed for large cubic inch small block Ford engines, as well as engines with high-boost superchargers or turbos, big shot nitrous oxide systems, and other mega-power combinations. They feature unique valve spacing, .750 in. raised exhaust runners, extra-strong castings, and thick decks for additional rigidity and gasket integrity, superior cooling characteristics, and, most importantly, excellent airflow. Trick Flow® High Port® 225 heads have top-of-the-line CNC Competition Ported runners with a high-resolution surface finish for maximum airflow and power over the entire rpm range. The entry into the intake runner has been reshaped to help seal the area along the port roof and thicker port walls, increase strength, and provide additional material for porting. Plus, interlocking ductile iron seats are used to handle the stresses of high-heat, high-horsepower applications. Other features include fully CNC-profiled combustion chambers with port-to-valve seat blending (bowl blending) and raised valve cover rails. Trick Flow® High Port® 225 cylinder heads are available fully assembled or as bare castings.
