    These work great in high RPM/Power motors.

    It prevents the sleeves from moving at high RPM. It closes the gap between the Cylinder walls and the rest of the block.

    Yes, you are better off taking it to a good machine shop so they can istall it correctly because it actually fits so tight that the cylinders might need some honing due to the blockguard not letting the cylinder walls expand when it becomes extremely hot.
