Opinion on Engine Buildup - Short Stroke 2.5L

Ok - I've got most of the components together for my short stroke 2.5L build up (actually a bit bigger displacement) and came into a bit of extra $$, so it may take place sooner than I thought. I'd really like any helpful tips, opinions or suggestions on the components to use. So far I have:

7R Case (To have case mods done)
66mm Counter Weighted Crank
92mm RSR Pistons / Cylinders (Cylinders to be replated by EBS)
Early S Cams
Cylinder Heads with 38mm ports
RS Distributor
40mm Webers

I guess some questions I have are:
- Can I use a stock oil pump from a 2.7l engine? Would a 964 pump be better?
- Are 38mm Intake and Exhaust ports to big for mostly street use?
- What head studs to use? Steel, Dilivar, ARP/Raceware?
