What's Included
- Two heads with valves, dual springs, chromoly retainers, hardened keepers and bronze guides
- Rocker, exhaust and intake studs
- Custom intake gasket
Not Included
- Lash caps (P/N 00-4006-0), required with stainless valves
Why It Matters
The D7000 port sits between Stage 1 and the full Stage 3 wedge: serious racing-grade flow without going all the way to the maximum port. Cutting it on a 5-axis CNC mill gives repeatable flow from port to port.
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.
