Both statements are correct. Technician A is correct in stating that block mounted cams convert rotary motion into linear motion of the followers, which is a fundamental principle of camshaft operation in many internal combustion engines. Technician B is also correct in stating that overhead cams convert rotary motion into rotary motion of the rocker arms, which then act on the valves. This is a common configuration in overhead camshaft engines, where the camshaft is located above the cylinder heads.
