Find a 55-57 Chevy Forum..You should be able anything you want !!

Suggest sending the carbs to Val Headworth and have them fix them up right!

For camshafts recommend Bullet Cams.
They have many of the experienced Cam Makers from Lunati, Comp, Crane and others.
That also know your combination and history on making those cars run.

As a VERY BASIC rule of thumb, 1 HP per CID, all else being equal. In this case, your talking 44 cubic inches or 44 HP. That's "pretty close" to what Brad said; 2 1/2 tenths. And he has real world experience. That just allows you to do some quick calculations to determine if the CID increase cancells out the HP or weight increase. And of course you should easily make 1.25+ HP per CID for any class engine.
