What header gaskets?

I need to replace my header gaskets on my '98 LS1 with XS Power headers. It only took a couple of months for a leak to develop on the passenger side and the bolts weren't really loose. What gaskets should I use? Any suggestions would be appreciated.

I use the stock GM gaskets and have never had a leak in the 10-1/2 years that I have had headers on the car.

Link doesn't work for me. Anyone have the GM p/n?

Did some parts research and come up with 12558573? Is this correct?

12617944 is the new number but there may be 12558573 still in stock which will work fine.

Either one.

If anyone has a hard time getting an oem gasket, look at Victor Reinz brand gaskets. Theyre carried by many autoparts stores and are oem or better quality. In fact they make many oem gaskets.
