What do I need for a Mini-Me?

The car I bought a while ago that I never drove much has a d15b7z6 mini me swap.
I turned it on about a week ago and it ran fine just needed oil.
I come back today and see oil, sludged, on the tranny and the block.
I had this problem multiple times on my old z6.
I dont know much about mini me swaps
Basically I just want to know:
-Which Head & VC Cover Gasket Do I buy (for b7 or z6?
-Sparkplugs
-What Timing Belt to use, and Whats the timing set to
- also anything else just because I want to do a tuneup and fix the damn
thing.
Any input would be greatly appreciated
