AKRON,
OH. Trick Flow Specialties introduces the best-flowing cast cylinder heads available for naturally aspirated LT1 engines: Trick Flow GenX™ Street/Strip Cylinder Heads. Out-of-the-box, these heads are easily capable of producing well in excess of 500 naturally aspirated horsepower.
The GenX Street/Strip Cylinder Heads for GM LT1 feature 54cc combustion chambers to maintain the factory 10.25:1 compression ratio, but have CNC-profiled and bowl-blended combustion chambers to maximize performance.
The heads have 21° valve angles—reduced from 23°—to increase piston-to-valve clearance and unshroud the chambers for better flow.
GenX Street/Strip Cylinder Heads for GM LT1 also feature 185cc intake and 67cc exhaust Fast As Cast™ runners that duplicate the port shape and profile of fully CNC-ported runners. The result is near CNC-ported power and performance for the same price as standard cast cylinder heads—and the best-flowing cast LT1 heads available.
The fully assembled heads come with stainless steel 2.020" intake / 1.600" exhaust valves, GM LS-style 1.300" double valve springs, chromemoly steel retainers and locks, guideplates, and ARP 3/8" rocker studs. In addition, these heads retain the use of all stock sensors and fittings. Bare cylinder head castings are also available.
