LS blocks with the same exhaust ports as L76?

Which motors share the same exhaust port footprint? As in, where the manifolds/ headers bolt up.

All standard port LS engines have the same dimensions as far as bolt pattern and port location (LS 1, 2, 3, and I believe 6). I say standard port because you can get into exotic Raised port, or Spread port exhaust, however, these are not production car heads such as the L92.

1967 Firebird 400/4spd all numbers matching
1965 Pontiac GTO 389 4bbl 4sp.
1971 Camaro Pro ET Drag Car
1970 Camaro real Z-28
1963 Impala Super Sport 409 dual quad 4 spd
1967 Chevelle SS396 4sp clone
2009 White Pontiac G8 GT.........shockingly stock.

Production exhaust locations are the same. Intake ports are different however.
