For builders seeking real gains without breaking the bank, the AFR Enforcer heads offer a premium-aluminum, street-capable design that bridges the gap between stock castings and full CNC race heads. These heads feature permanent-mold “As-Cast” surfaces in the intake, exhaust, and combustion chambers—delivering consistent port geometry, repeatability, and solid performance right out of the box.

The AFR Enforcer SBC heads (Small Block Chevy) are particularly compelling, with 195 cc intake runners, 2.020-inch stainless intake valves, 1.600-inch exhaust valves on 8 mm stems, and flow specs reaching 251 cfm intake and 197 cfm exhaust at .600″ lift. These heads support hydraulic roller or street-style mechanical cams up to .600″ lift and RPM levels in the 6,000+ range without compromise.

One big advantage is the parts set included in the fully assembled units: ARP rocker studs, PAC/AFR dual springs, Viton seals, hardened spring seats, adjustable guide plates, bead-lock valve locks, ductile iron seats, and stainless valves. In other words, you get hardware that matches many AFR premium heads—just without paying for porting you may not yet need.

Whether you're building a 350, 400, or stroker SBC under 6,000 rpm, these heads deliver impressive value. With reliable flow, durable components, and budget-conscious pricing, they’re ideal for street cars, mild race cars, or anyone who wants to upgrade from tired OEM heads without overspending.

The AFR 195 Enforcer heads are one of the most popular configurations—assembled, straight-plug, and ready to bolt on (sold per head). These heads give you the performance jump you want, now, without the cost or lead time of fully exotic CNC heads.
