How It Compares With the Alternatives
Compared with re-facing the original valve
Re-facing can be done once if there is material left on the margin, but a burnt exhaust valve has usually lost too much.
Compared with a complete head assembly
A complete head is faster but far more expensive than replacing the valves in a sound casting.
Fitting and Service Notes
- Replace the valve stem seals and check guide clearance whenever valves are changed.
- Lap the valve to its seat and confirm a continuous contact band.
- Check installed stem height after lapping; too much removal moves the valve train geometry.
- Set clearance after assembly and re-check after the first heat cycle.
