Overview

Our High Output 2.0”Twin Cam© heads are designed for larger displacement, 4 inch+ bore engines. Both ports feature more extensive CNC porting and the intake valve seat is changed and valve size is increased to 2.0 inch. The combustion chamber is enlarged to 97cc and un-shrouded for increased intake flow. Stainless steel valves, Step-Lock guides, Viton® seals and high lift valve springs are installed after the seatwork is finished on our Serdi equipment. These heads are also machined for and include manual compression releases (on non-ACR equipped heads). Used on our 4.125" bore Muscle 107”, 117”, 120” and 124” engine kits. This is the finest modified Twin Cam© head you’re likely to find anywhere!
