Courtenay sport cs15 head with over-sized inlet valves
this head has only done 100-150 miles before the car was broke
Courtenay Sport CS15 will give approximately a 15% improvement in both torque and brake horsepower - right across the board! It comprises of a head, which has been overhauled, with new stem seals. The valves are reprofiled in the stem and the head. The ports are reprofiled (not merely opened out) and the seats recut with compound angles. The ports and combustion chambers are then not polished, but sandblasted specifically to take away the polishing effects of the machining work. This has a major influence on improving the torque, BHP and fuel economy.
