The following table is a handy reference for servicing Command twin cylinder heads. It includes the kit
part numbers for all levels of service, from simply changing the head gasket to replacing a complete head
assembly.
1. If the head is reusable, order only the gasket kit. Each gasket kit includes the installation instructions,
cylinder head gasket, intake manifold gasket, exhaust gasket, intake port O-Ring, four M8X1.25 Flg.
Nuts, and four 8.6 mm Flat Washers.
2. If the the valve train components are reusable, order the gasket kit plus the head kit. The head kit
includes the head and exhaust studs. The RFI head kits include the head, the RFI flexible sleeve tube,
spark plug, ignition module, and installation instructions.
3. To replace a complete head assembly and valve train components, order the gasket kit, head kit, and
valve train kit.
NOTE: Each kit services one cylinder. To service both cylinders on a twin, order one each of the
cylinder head kits, two head gasket kits, and two valve train kits.
