Because the ports are in different locations.
An LS head looking from the exhaust side is I-E-I-E-I-E-I-E where as a windsor head is E-I-E-I-E-I-E-I.
That difference alone would require a custom billet camshaft. Unless you want to cobble together the whole thing and try to adapt an ls cam into the windsor. I don't have an example of both here right now to even say if it's doable.
When the ls7 came out in the corvette, I was looking at finding one of those wrecked for cheap and stealing the engine and dry sump.
I'd then swap on a set of alloy cleveland heads, some compatible pistons, custom intake, and a camshaft to make it all go. 427 cubic inch, titanium rod cleveland on the "cheap". The bore spacing of the LS is larger then that of the ford engines, the head bolt locations are also slightly different, so you'd have to use some magic to get it all to work. I was thinking offset dowels and a die grinder on the bolt holes might get you close.
The problem is, those wrecked ls7 engines aren't cheap. So by the time you do all the custom work to adapt the cleveland heads, you could have used a dart block, ls7 ti rods, and off the shelf parts and had the same thing.
If you did that you would still need a custom cam wouldn't you?
