yes. But you will have to buy new valve covers and the brackets for the coil packs to mount.

Does a bear poop in the woods? Of course you can use the later model heads. But they flow the same, so if you are in the market for some heads check out Patriots stuff. The 98 heads are cheaper if I recall correctly. It's not like the different valve covers cause major oil leakage or anything.
