How fast can you go with a Magnum? Who has the quickest setup?

How fast can you go with a Magnum? Who has the quickest setup?

So... lots of good thoughts and suggestions in your post, @rumblefish360 but I just chopped and reorganized a few pieces to hopefully narrow some questions down. :D

The first bottle neck the Magnum engine faces is ether the heads port flow or the OE low compression ratio.
...
I plan on use of a Magnum block but not the heads.

Also, if I have this right, there are only 2 aftermarket heads for the Magnum. 1 iron, 1 aluminum. There pretty limited vs. all out race heads...

So if I understand correctly, stock heads have limitations on lift, valvetrain stability and compression, don't respond well to porting, have low compression...

So aftermarket heads are kind of a must-do, correct?
But...there are only two options; EQ and Edelbrock....right?
EQ:
JEGS EngineQuest Mopar Magnum Cylinder Heads | JEGS
Edelbrock:

So which ones are you going with?

You'll need to get into the bottom end when cam specs exceed the stock pistons ability to handle ether the long duration holding the valves open or the lift limitations of the OE piston.

Has this been explored? Are there piston/cam combinations that have worked for folks?
