Here is Spreed Sheet with a few radiator manufactures related to LS swap or not:

General rule is if the Radiator comes with a steam port it is LS direct swap,
you even have the option sometimes to indicate where you want your port/s

If no Steam Port you can still use the radiator in a LS swap you just need to
add a steam port at the highest point in the motors water line.

There are many more manufacturers I am sure, please feel free to add
to the list! I'ts a rabbit hole if you let it be.

Thanks again to LeeGreen And DSRaven for all the technical support,
between the Mac ,Touch Pad, Mouse and general lack of abilities we
made this small spreadsheet happen.
