New at Summit Racing: Chevrolet Performance Fast Burn Aluminum Cylinder Heads for Small Chevy

These fully assembled Fast Burn cylinder heads from Chevrolet Performance are designed for Gen 1 350-400 c.i.d. Chevy V8s and can support engines making up to 500 horsepower. The combustion chamber shape allows a more complete burn of the air/fuel mixture using conventional flat top pistons, resulting in higher cylinder pressure and more power.

Chevrolet Performance Parts' cast-ported technology incorporates improvements in airflow, combustion, and cylinder fill within the casting, giving you maximum performance out of box. Additional porting is recommended for all out race applications. All Fast Burn heads are CNC-machined to exacting tolerances, eliminating the need for the blueprinting. The Fast Burn Cylinder heads are drilled and tapped for Vortec and raised port manifolds, and accept flange-mount or centerbolt-style valve covers.
