Just wondering if the 98 WR 400 has the 5 valve head design...also would a 99 Grizzly have a 5 valve head? Thanks :)

Yes, all 1998 and newer WRs have a five valve head.
As for the Grizzly, if it is the 600cc I don't think it does. But, the Grizzly 660, which came out in (I think '02 or '03), has the same engine as the Raptor 660 which has a 5 valve head.

Yes, and I think they were stainless valves, then when the 426 showed up, they were all titanium
