§ 02 / About this part
What it is
The KIBBLEWHITE VALVE GUIDE INTAKE C630 BRONZE, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
These C630 bronze guides are pressed into the cylinder head to provide a stable path for the intake valve stems. They are essential for heat dissipation away from the valve and into the head casting. Worn guides lead to oil consumption and poor valve seating, which kills power. These are a must-have for a professional top-end overhaul. The bronze material offers superior thermal conductivity compared to standard cast iron. Professional fitment is recommended as these require precise pressing and potentially reaming to achieve the correct stem-to-guide clearance.
