How can I tell if my engine has a flat tappet or roller camshaft?

You will need to remove the intake manifold or timing cover to visually inspect the camshaft. Factory roller camshafts have a different design at the lifter interface compared to flat tappet camshafts. Many engines from 1985 onward gradually transitioned to roller cams.
