Yeah, I hope you're not a professional comedian....
However, you may want to do a little research before you pass it off as a quip...
Considering the LS was a "clean-sheet" design, it's funny that GM used a lot of SBF/Cleveland engine traits....simliar deck heights, same intake port CSA between LS7 and 351C-4V head, similar valve sizes, etc. The head actually is so close that it will bolt right to a Cleveland or Windsor block without issue.
The LS also shares a skirted block, like a Modular Ford or a Ford FE. I guess GM was getting the hint.
