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.
These new fully CNC-ported heads feature 215cc intake runners, 80cc exhaust runners, 64cc combustion chambers, 2.040" intake valves, 1.575"exhaust valves, bronze valve guides, and ductile iron intake and exhaust seat inserts.
Assembled heads come equipped with stainless steel intake and exhaust valves, 1.300" dual extreme pressure (150# seat 450# open) valve springs for lifts up to .650", viton seals, machined spring locators, 7 degree titanium retainers and machined steel locks.
One last important feature of this 13.5* head design is the valve drop. This head features a .155" valve drop on the intake, a stock 5.7 head with 2.00" valves has around .150". What this means is you can run this head on stock pistons with large camshafts and still have more piston to valve clearance than a stock head and also more compression.
Note: A roller tipped rocker and .100” longer than stock pushrod is required with these heads.
