For a full IRA withdrawal 'in-kind' where the assets are not liquidated, but leave custodianship: Does the IRS require immediate payment or is monthly w/holding accepted?

I am considering completing this transfer into a custodian IRA LLC or just paying the taxes flat out due to the maintenance requirements of custodianship. I would prefer to pay the IRS over the next several months of paychecks through withholding if possible.  I do not want to sell the assets in the market due to market conditions.
