They have 3 angle seats and waisted a stem for durability coupled & light weight.These valves are suitable for use in cast or bronze guides and are used in our own cylinder heads.

Can be worth up to 4hp and 4lbs ft torque on a mildly tuned 1275/1380 motor. Titan Full roller rockers have a roller on the rocker tip and the rocker itself has a roller bearing on to the shaft. This Gives near frictionless movement. Roller tip rockers just have a roller on the tip of the rocker and have a normal bush on to the shaft.
