Do I have to bore my engine?

I have a 1997 Oldsmobile 88 base model with a 3.8 Series 2 engine. I want to replace the Head Gaskets only. I was thinking about doing it like this....You know remove the Heads, get the old gaskets off, then install the new gaskets, put the Heads back on. With the new Head bolts torque to OEM Specs. Is it a requirement, a necessary step to bore my cylinders when putting in new head gaskets? Head gaskets looks fine on my car right now, no problems that I know of. I just want to replace them. I'm also going to replace my valve cover gaskets, timing cover gasket, and intake gasket. Whats the point of boring my engine if I'm not installing new pistons! I hope the answer is no. Thanks for any replies.
