Why It Matters
The L7 is one of EMPI's high-end racing CNC ports, a flow profile optimized for horsepower-per-displacement on high-RPM Type 1 engines and carrying forward much of what DRD Racing Heads offered. It is cut on a 5-axis CNC mill.
Installation Notes
- Lash caps (P/N 00-4006-0) are required for all stainless steel valve applications — sold separately.
- 12mm long-reach spark plugs must be used in place of stock Bosch plugs.
- Verify rocker arm geometry and check for coil bind with dual springs.
