Description

Serious street performance, modified oval track and bracket racing. Mid-range to 7,000 RPM. Best for 400+ cubic inch engines.

Dart’s SHP (Special High Performance) 23° 220cc cylinder heads provide an affordable option for larger displacement street performance engines. The SHP is designed to work with most off the shelf components.

The SHP head’s precision cast ports are designed to offer excellent flow and power without the need for CNC porting. Optimized chambers increase combustion efficiency and multi-angle intake seats and radiused exhaust seats dramatically increase performance. Manganese Bronze valve guides increase the life of the head.

Heads are sold individually.
