470 looks like they didn’t even try.
You got me scratching my head so I dug out the old 680 workshop manual.
Really obvious how poorly the studs are spaced on the engine’s left side.
Also the “bulges” in the block that I mentioned previously can be seen, there’s not much metal around the studs.
The whole top of the block would try to lift off along a crack line at the bottom of those bulges.
Cleaning the block surface while working in-situ can be a pain that’s for sure.
