Increase performance and save yourself the hassle of having the stock heads reworked by replacing them with AFR’s 225cc Mongoose Strip Cylinder Heads.
What They Are: AFR 225cc LSX Mongoose Strip Cylinder Heads for GM LS
Why They’re Cool: The new combustion chamber design with a double quench area generates huge low and mid-lift airflow numbers. The heads are ideal for aggressive, normally aspirated 396-427 cubic inch stroker engines and feature 2.08 inch (intake) and 1.60 inch (exhaust) valves, 225cc intake/85cc exhaust runners, ductile iron interlocking valve seats, and three combustion chamber volume options (62cc, 65cc, or 72cc). Cylinder heads are available fully assembled or as bare castings.
Applications: GM LS1, LS2, and LS6
