This is what I am currently using. It was one I got from my Dad after he passed. 548B63C4-1987-4032-92A2-0C099DE95CC4 by Jody Collins, on Flickr

A cup plug will do it.
A stage I porting should get you 320 cfm or more. That will give your 445 the capability to make an easy 500 hp. I just did a 390 with street porting of Edelbrock RPM heads, Port O Sonic, and made 479 hp. Nothing fancy. A 445 should easily top that with another 50 hp. Joe-JDCThanks Joe. I'm sending you a PM for some info.
A good valve job and bowl blending helps quite a bit.
Full porting or CNC porting is costly - depends on the power goals.
Before I spent the $$$ CNC porting Edelbrock heads I would buy some TFS heads instead - smaller port volume and more flow.
One can always sell the box stock Edelbrocks.
This all depends on what you want. 400 HP? 500 HP? 550 HP?

Some good information in this thread from 3 years ago. If you are a DIY guy have at it, kind of fun, get a nice 3 angle valve job as well.
I basically port matched and did what was described in the thread and my 445 pulls hard.
For me, really hard to put something together with obvious physical port mismatch then add gasket misalignment on top of that.
I chased sharp corners and matched all the way from carb base plate to chamber and am happy with it.
