Carburetor Question - Is this a good call?

Hey all,

So i took the carb off to check out the jets and get some info for the thread and to do my own investigations.. theres a riser / adapter plate for the holley to carter-type bolt holes on the intake manifold and the gasket stuck to the manifold which showed me the following...

So i peeled that off and cleaned it up with a wire wheel and put it all to bed. My first step is to find a new adaptor plate (any links all?) and get it on there... i cant believe its been like this forever
I don't think there's any way the motor would run right with all that mis-matched junk under the carb????????
