Dart’s SHP cylinder heads provide a low cost option to those looking for the weight savings of an aluminum head for a street performance engine.
The SHP is cast from A356-T6 aluminum and designed to work with most off the shelf components, so you won’t need to worry about acquiring costly custom components.
- Bolt on compatibility: Standard valve angle and spacing are retained to allow use of off the shelf pistons and valve train components
- Multi-angle intake seats and radiused exhaust seats dramatically increase air/fuel flow
- Hardened exhaust seats are compatible with unleaded gasoline
- Manganese bronze valve guides extend cylinder head life
- Machined for 1.250 or 1.437 diameter valve springs
- Straight spark plug configuration
