Trick Flow 265cc GM LS Cylinder Heads
PN: TEA-LS265TF-CUSTOM
1997 & Later Large Bore GM LS Engines
The 265cc Drag head. Our largest offering in a Cathedral Port design. Built using Trick Flow's "LSX-R" casting. The casting has raised spring pockets, rocker pads, and valve cover rails to allow for high lift cams and valve train components. It is only available in a 6 bolt version. This head is designed for drag race only and uses our competition only 55 Deg. Valve job and Titanium intake valve. This creates great airflow benefits at high valve lifts -(.700-Up). We also assemble this head using the best components Victory-1 valves, .850" PAC springs, and Manley Retainers, locks, and locators. We also can custom build any combination you request too. Head comes standard with 64cc chambers.
Options like beryllium copper seats, Springs-PSI, Comp, Nextek, etc. Are available.
New: Larger Nitrous exhaust port now available.
