Technician A is correct because measuring camshaft journals for out-of-round and taper is a standard procedure to ensure the camshaft is within manufacturer specifications for proper operation. Technician B is also correct because in Overhead Valve (OHV) engines, it's common for camshaft journals to be of different sizes to accommodate the varying loads and operational requirements along the length of the camshaft.
