true..
if the head matches the 3 angles, it is simply another ridge of seal. Given precision of today, one could make it so many angles it looks curved...no angles about it. The ridges aren't good, but for aluminum heads and stuff, it all takes peacefully...no matter what they do for angles jobs..

its like 8 bit pixelated to 64 bit high definition..not many car parts have evolved the same yet. I could guess 3 angles will fade away...
