Same? No. Close? Yes.
The B16A will run a little lean for a B18C, while a P61/B17A will split the difference. I would still suggest a V-AFC or similar and some dyno time to perfect the fuel curve. The ignition timing is similar through all three and will work fine (although a stand alone would be the ideal setup in any case.)
