HRC cam carrier shims are required to set the correct backlash on the cams after skimming the heads.
Available in various thicknesses.
Increased performance & durability in race conditions.
Bronze & copper seats dissipate heat much more efficiently than steel, and are also more suited to the factory titanium valves.
The porting adjacent to the valve seats is particularly sensitive to change, and great care must be taken when modifying this area.
Remove burrs from edges or shoulders on the ports by using a stip of sand paper and sliding it over the surfaces carefully.
