I guess, but in reality, no. A hemi has is more domed shape with a steeper radius.

But of course, with multi-valved heads, the natural tendency is to make a more hemisperical head

Didn't that article mention cost being one of the factors for leaving it off the current engine? Seems safe to assume that ford wanted to have a quick way to answer to any new engines chevy busts out and also most likely the cost of the tech will go down with time too.

Using the term "hemi head" in this day and age is just silly. The 'Hemi' used by Chrysler isn't even hemispherical anymore...it's just a brand name, not a technical term.

I see it as akin to interchaning 'NOS' and 'nitrous'. Use of the word NOS when referring to a nitrous system just makes you look stupid - this really isn't any different.

Yes, the cost to time curve could also be a factor. But in reality, it could more likely be that Ford is not yet ready to offer the Coyote with direct injections because they could still be hammering out bugs with the direct injectors that specifically will go into these engine. So, to offer the new 5.0 in the 'Stang when the 5.0 was so long in the development, Ford made the decision to cast and mill heads without the direct injection ports for now and satisfy 'Stang fans while still giving themselves time to continue to make the Coyote direct injection work.

If any of these are the case, Direct injection could be ready to deploy when Camaro & Challenger up the ante. Or if Direct injection is already perfected for the Coyote, but cost is a factor, Ford could be saving up money from the profits of current vehicle sales so that they will have enough money to retool or buy additional production machinery to make these injectors en masse in time for mass production of new 'Stangs with them in.

The other thing I was thinking when cost of adding FI is that Ford most likely had a price point set for the 5.0 and possibly wasn't able to hit it when FI was added to the cost of the engine.

Not to say your ideas are wrong, this is just another possibility that came to mind.
Guess we'll never know.

No, that is true too. But also, the Coyote is still brand new and it is still at a rather amortized state of R&D investment cost that Ford is not yet making money per unit engine MSRP. But given that the Coyote will be widespread even in F150 trucks and other intermediate Ford coupes and sedans, once the engine become more widely sold, Ford will actually start to make more money on it and as the engine also becomes cheaper to manufacture, Ford could also drop the cost of the engine and use some of the savings to add in FI & DI in the future while still offering the car at a similar MSRP
