yes, but you will need valvecovers, and coil pack brackets, and mod the pcv system

i thought b/c of the different bolt patterns(98 - perimeter vs 99+ center) you couldn't use differen't heads...or are the blocks drilled for both??

The head bolt patterns are the same, it's the valve cover bolt patterns that are different.

What head gaskets would you use though? Ones for a 98 or the 2000?

I think 98. Call a sponsor and find out for sure.
