Trick Flow® GenX® 185 Cylinder Heads for GM LT1 TFS-3041B008-M54

Trick Flow ® GenX ® 185 cylinder heads give you performance that closely matches CNC-ported cylinder heads—for about the same price as ordinary cast heads! Designed for naturally aspirated GM LT1 engines, the GenX 185 heads retain the factory compression ratio and have standard resolution CNC profiled combustion chambers to amplify performance. The valve angles were reduced to 21 ° from stock to increase piston-to-valve clearance and unshroud the chambers for better airflow. Power-building Fast As Cast ® runners duplicate the profiles of fully CNC-ported heads, resulting in high airflow rates without costly CNC-porting. These heads accept all stock sensors and fittings.
