Your mechanic was referring to the "notched 853" castings. The deck of the head has a notch on it and requires a special "notched" gasket. It's not a big concern really. I'm about 95% sure your '98 heads (806s) don't have a notch. As for what gasket to use, you can use the notched gasket on any year LS1, but you cannot run notched heads without the notched gaskets.
Best of luck, post up any more Qs you have. Also, it sounds like your mechanic has some LSx experience from the question you asked. That's always a good thing.
