  1. Ream the valve guide as necessary to achieve proper valve stem-to-guide clearance with the new, oversized valve stems.
  2. Always recondition the valve seat after reaming the valve guide bores or installing new valves.
  3. Replace the cylinder head if the valve guide cannot be repaired or reamed to accept an oversize valve stem.
