One other issue with putting it that far to the pass side is centerlink/idler arm clearance to the oil pan. Mine comes VERY close at full lock. You may want to bolt up the steering linkage to make sure it clears
Honestly, I would just bolt the trans up, whatever manifolds/headers you intend to run, and steering linkage, and lock the engine in wherever it clears everything. Height-wise, put it as low as you can without having clearance issues with the centerlink/idler arm. Done and done
***EDIT*** - Also, make sure you bolt up an oil pump. Mine comes pretty close the DS K-member.
