Edelbrock E street 84cc would be my suggestion.

I have a cracked cast head and what about Pro Form or is there another Aluminum head I want to go back to factory specifications I'm not really sure what you mean by this. Of course an aftermarket aluminum head will not be factory spec. There are several aftermarket aluminum heads that I would consider factory replacement and all of your stuff will bolt back on without issue. Some aftermarket look like factory, some do not, some have angled plugs, some do not. There are a few different combustion chamber sizes available too. This will be a great opportunity to for you significantly up your engine performance by simply making a good choice here. It will be difficult for us to tell you what that is without knowing exactly what your goal is. If it is to simply look as close to factory as possible, 440 Source's Stealth head is an option.

Rocky Edelbrock did make some like that. They were sold through MP as the "452" head.

The 84cc E street head I recommended has straight plugs.

Is this motor what was in the car when it was running at the drag strip? If it's not a factory motor then you really do need to know what pistons and cam are in it. You don't want to end up bolting an aluminum head on that has closed chamber with high compression pistons designed for an open chamber head.

A .030 over 440 with pistons .005 down the hole, 6cc valve pockets, 84cc heads. .040 gaskets is right about 10:1.
With closed chamber aluminum heads it will have proper quench.
That’s how I’d build it.

That’s how I’d build it. Same. I think that this is exactly why Eddy built this 84cc head. Common 2.06" something piston at zero deck and 0.040 gasket.....perfect CR with quench. Don't put too small of a cam in it. OP - have Dwayne spec you a cam too.

913.4- swept 84.0- chamber 10.0- 4.41 x 040 gasket 6.0-valve pocket, SRP flat top 1.2-.005 deck 1.0-area above top ring ————— 1015.6- total 102.2- total minus swept ————— 9.937cr
Swapping the SRP piston for an Icon piston with a 4.5cc valve pocket would bring the cr to 10.07. Taking that 10.07 package and reducing the deck height to zero brings it to 10.16.
