AFR’s latest LS3 Enforcer cylinder heads draw inspiration from our LS3 Mongoose CNC 12° cylinder head. The all-new LS3 Enforcer head is offered in an unassembled or fully assembled configuration, including the same top-tier components found in our premium CNC ported heads. These components include PAC Racing Springs, titanium retainers, Viton valve seals, hardened spring cups, ductile iron seats, and AFR stainless steel 8mm valves. Featuring a 238cc intake port, a 92cc exhaust port, and a 72cc combustion chamber, our cylinder heads are designed to meet the demands of today’s high horsepower LS engines.
Available for individual purchase, these heads are manufactured using a permanent mold casting method, resulting in precision-engineered as-cast surfaces on the intake runners, exhaust ports, and combustion chambers. The LS3 Enforcer heads stand out as an ideal choice for those seeking an upgrade to a modern port design, complete with reliable components meticulously chosen by our esteemed engineering team.
