  2. Recondition the valve guide hole of cylinder head so that it can match the newly press-fitted oversize valve guide.
  3. Using the SST (09221-3F100A, 09221-26000), press-fit the valve guide. The valve guide must be press-fitted from the upper side of the cylinder head. Keep in mind that the intake and exhaust valve guides are different in length.
