2004-2007 Cadillac CTS-V Cylinder Heads
Trick Flow's latest offering for the LS-1,2,and 6 engines. This head has been designed on a 13.5 degree valve angle, and uses stock length LS-1 valves and valvetrain components for use with hydraulic roller cams. The flatter
valve angle allows for more piston to valve clearance with a 2.040" valve than a stock 5.7 head with a 2.0" valve. In order to maximize midlift airflow and improve combustion the spark plug has also been rotated away from the
intake valve seat which eliminates the plug boss and coupled with the 13.5 degree angle makes this head flow more through the midlift than everything else available. Trickflow has built this head with a .600" thick deck to
provide ample deck thickness for head gasket integrity without compromising cooling ability. We currently offer port designs to fit 3.9, 4.00, and 4.125" applications. Note: A roller tipped rocker and .100" longer than stock
pushrod is required with these heads.

Patriot Performance began its business with revolutionizing the CNC cylinder head market. They are one of the largest suppliers of ported LS, Modular Ford, SBC, SBF, BBC, and other heads in the nation. The porting
of performance heads has always been part of attaining maximum horsepower. Patriot Performance designs their own CNC programs to port the chamber, bowl, and runners to attain maximum air and fuel flow. Slight alterations can affect that flow tremendously. Patriot's ported heads resemble works of art after they are machined. Along with ported heads, they offer our Freedom series heads. With the introduction of our Freedom series, Patriot brought a revolution to the performance head market… performance and quality at a price everyone can afford. To optimize the flow in all of these heads, we have spent countless hours on proprietary valve seat designs. These designs have been developed to work along with their custom designed chambers and runners. All of Patriot's heads are built using the highest quality parts right here in the USA!
Things have changed…no longer is Quality, Performance, & Service reserved for those with huge budgets. Patriot Performance makes the products you need at the price you want.
