I recomend the 964 crank as it has bigger rod journals and is considered the strongest street crank we got. I wouldnt bore the case for larger cylinders because I have never seen or heard of one that didnt leak oil from the base gasket. A good set of rods are in order as well (Carrilo, Pauter, etc...) But it also seems like a lot of work just to be putting cis back on the motor. Would you consider EFI?
Base of cylinders won't leak if you use the 3.8 RS seals, you got to cut a grove inside of the case spigots, and use the RS o-rings.
