replace dohc with sohc

Is this a direct replacement? Bolt in? Will the computer have to be recalibrated? Please help asap... I also heard the sunfire engine is a direct bolt in...true or false?

Only a Saturn engine will directly install into a Saturn. Swapping a SOHC in place of a DOHC is not a direct swap either.
