Trick Flow GenX 205 CNC Ported LSX Cylinder Heads
Trick Flow Specialties Gen-X ported LS 205 cathedral port cylinder heads are fully CNC machined to significantly increase the performance of small bore 5.3l and 4.8l engines. Trick Flow engineers altered the valve angles from the factory 15° to 13.5° to decrease valve shrouding, increase mid-lift airflow and improve rocker arm to valve cover clearance. Top of the line CNC "Competition Ported" runners have a premium high resolution surface finish for maximum flow and performance.
The spark plugs were relocated in the CNC profiled combustion chambers to enhance mid-lift airflow and increase the rigidity of the casting for extreme horsepower applications. Material was added at the rocker arm mounting points to increase high RPM valvetrain stability.
Many valvetrain options from tool steel retainers and PAC Racing springs to inconel or titanium valves are available.
The Trick Flow GenX 205 LS cylinder heads are available fully assembled or customized to your particular project.
These cylinder heads are custom built per application and are not a stocking item.
