What is the current best kit for this job? Planning on doing LIM gaskets and new UIM. Anything else I should change well I'm in there?

Tis summer time and time to rip the 98 apart

GM LIM Alum frame gaskets - Need to make a trip to the dealer for those

Dorman help coolant elbows - Do I order those somewhere online or get them at autozone?

Autozone has them hanging on the wall display. You'll need the one with the orange/red o-rings, throw the one with the blue o-rings in the trash. There are two in the pack. IIRC, 98 or 99 and newer use both, but don't really need the 'blue' unless they pull the accessory bracket.

INTENSE has the aluminum gaskets as well.

zzperformance.com also carries the aluminum LIM gaskets.
