Trick Flow® GenX® 255 Cylinder Heads for GM LS3

Trick Flow engineers used the best features of OEM GM LS3 and LS7 cylinder heads, combined with their own race-winning engineering and technology, to create the GenX® 255—the ultimate ultimate square port LS cylinder head for 4.000" and larger bore engines. The heads feature fully CNC Competition Ported runners with a premium high resolution surface finish for maximum airflow and performance potential. Stock LS3 ports accommodate LS3-style intake manifolds and LS9/LSA blower assemblies. The valve angles have been changed from 15° to 12° to increase piston-to-valve clearance and allow the use of larger camshafts. The coolant holes through the head deck were redesigned to work with all LS head gasket and engine block combinations. GenX 255 heads are available with standard or 6-bolt per cylinder mounting patterns. Trick Flow GenX 255 cylinder heads are emissions-legal under CARB E.O. #D-747 for 2007-present GM vehicles with 6.2L engines. They are available fully assembled or as bare castings. Sold individually.

Trick Flow® GenX® 225 Cylinder Heads for GM LS2

Trick Flow GenX® 225 cathedral port cylinder heads are fully CNC-machined to significantly increase the performance of 6.0L LS2 engines.

COMP Cams Shaft Mount Aluminum Rocker Arms

COMP Cams shaft mount aluminum rocker arms are one of the most cost-effective ways to increase horsepower. These shaft rockers were designed using the latest in computer software and engineering. They center the roller tip over the valve tip at the correct time so that the roller tip is never more than 0.020 in. off-center of the valve tip. At the greatest load point, the roller tip contact is on the center of the valve. At valve closing, the roller tip contact is slightly behind the valve centerline. When the valve is at full open, the tip contact is slightly behind the centerline of the valve. The results are more horsepower and better performance.
