Is a 215 Dart Head to big for a 350 CFM carb? The motor would be 12-1 406 5.7 rod motor with a port matched intake.

215 would be fine. Big I'll agree, but not too big to make power anyway. You might have to turn a few hundred more RPM to make the comparable power though.

I would get the compression higher. And then get some more.

I think those would be way too big. I will trade you for a nice set of 305 heads that have been worked.
