High Port ® 225 and 240 Cylinder Heads for Small Block Ford Trick Flow has developed several fully CNC-ported versions of the High Port cylinder heads specifically for large cubic inch, large power adder, big shot nitrous oxide, and other mega-power combinations. High Port 225 and 240 cylinder heads for small block Ford have all of the same features of Fast As Cast® High Port heads—unique valve spacing, raised exhaust runners, extra strong castings, thick decks, superior cooling, reshaped intake runner entries, extra material for porting, raised valve cover rails, and excellent airflow—plus top-of-the-line CNC Competition Ported runners with a high resolution surface finish for maximum airflow and power over the entire rpm range. Cylinder heads are available fully assembled or as bare castings. Sold individually.
