Also, consider when just pulling the motor that you may need to remove more of the engine parts
(fan,pulley,water pump and radiator) to gain enough clearance to move the motor forward to clear the trans.With the trans attached you can get a much steeper lift angle to clear the engine bay.Hopefully you have removed the hood too.As JHM says remove the valve train if lifting with the head bolts. It can easily damage the rockers,etc. if the lifting chain or engine leveler twists.
