Jerry, do you have the "straight" Side Weber intake to check?
Are you going into production with this?Now it appears the 4 into 1 system will accommodate any stock intake manifold. Weber configurations will take minimal modification to the manifold.
The next step will be to test the header out on a dynamo meter. Comparing stock headers to this 4 into 1 composition.

Iirc i read on some performance study for rally prep the later cast header when port matched flowed as well as the series I/II 4 branch headersJerry,
I hope you have time to also run the the later cast iron 4-2-1 unit in your testing. Just a matter of testing comparisons using the same baseline engine so apples are compared to apples. That unit seems to be questionable to most looking for an upgrade - maybe correctly - but I don't recall anyone ever posting numbers from an actual, comparable test.
Thanks for your efforts,
