How should the Exhaust Valve and Intake Valve be inspected for signs of damage and wear on Lincoln LS?

Inspect the valve, searching the end of the stem, valve face and edge, valve head, erosion, warping and cracks, and valve margin, searching the valve margin in evidence of wear.

How to Adjust the Intake Valve and Exhaust Valve Clearance on Lincoln LS?

In order to clear the valve clearance, take timing chains out and measure individual valve clearance using a feeler gauge prior to the removal of camshafts. Record measurements, and then de-shim and camshafts. Select shims using the formula to measure clearances desired. Install new shims, camshaft, and remeasure new clearances and then re-install timing chains.
