During the development stage, Trick Flow engineers determined that the valve angles needed to change from 15* to 13.5*. This change decreased valve shrouding,increased mid-lift airflow, and increased rocker arm-to-valve cover clearance. Testing also proved that relocating the spark plug position in the combustion chamber further enhanced combustion along with mid lift airflow and improved the integrity of the casting in the chamber area. Trick Flow also added additional material to the decks (.600") and to the rocker arm mounting pads to improve high rpm valve train stability.
Fully assembled with Ferrea valves, titanium retainers, Gold Extreme springs (hyd roller), machined steel locks.
Our biggest cathedral port offering, this is a larger version of our 235 head which uses 2.100" and 1.600" valves. Optimized for large bore (4.155" and up) larger cubic inch strokers. 70cc chamber is standard.
Combine this with an LSX block and build the ultimate large cubic inch monster.
Note: A roller tipped rocker and .100” longer than stock pushrod is required with these heads.
