 I would not mess with the Dellortos off the bat. Rather, I would work some of the other angles to get more power; Raised compression - I believe you can get 10:1 or more with the 2.2 strokers. Delta only offers 9.5:1 for a 2 liter build...

Three angle valve job, gasket matching, porting, K&N air filter, cams. How much do you want to spend? Apparently a great deal if you are going to build a stroker.

There is no doubt that you can get more high RPM power with the Dellorto, as the jet is centrally located, as opposed to the side jet in the Zeniths. But the Zeniths are so much simpler to tune that they are good for debugging your build, and they offer a good balance of power and economy. After you get it all running to your satisfaction you can swap in the Dellortos knowing that the the only tuning needed is the carbs.

Raised compression is the single best thing you can do. It adds power from idle to red line, and improves fuel economy - nothing else you can do will be as satisfying.
