Bowtie Race Cylinder Heads

Bowtie Race Cylinder Heads
Monster-cubic-inch stroker Big-Blocks need lots of air to maximize theirperformance potential and Chevrolet Performance Bowtie race cylinder heads are designed for that task. They are made of 356-T6 aluminum with huge, raised intake ports, larger valves, smaller combustion chambers and two additional head bolts for increased clamping force. The runners are purposely left smaller, so there is ample room for custom porting by the engine builder.
