Collection: Cylinder Heads

Aluminum cylinder heads from Air Flow Research for small block Chevy, small block Ford, big block Chevy, big block Ford, LS and Gen 3 Hemi. The range runs from 180cc SBC street heads through Enforcer, Eliminator Street and Eliminator Race heads to CNC-ported race heads, with 58cc to 75cc chambers, plus complete AFR top end kits.

Choose by intake runner volume, chamber size and valve angle: smaller runners keep velocity up on street engines, larger runners feed big-inch, high-RPM builds. Check spring specs against your cam lift. See Air Flow Research and Valves and Hardware.
