If you have, or will be adding a coolant re-route, it is best to use the '99 head gasket. If not, then the '02 head gasket has some non-reroute flow improvements to cylinder #4.
What Borka said. Though I'm pretty sure the difference in CR is the pistons, so you could swap them. Job just grew... If you are Forced Induction, the 9.5:1 will be a good thing.
