i asked about that ages ago on RSC. Noone knew. best guess was that it was where the head was clamped during manufacture or something

I initially though it was to shoe maximum skim depth or something, but its kind of deep for that!

the one in the peak to the side of the spark plug hole.

best theory I can come up wiith and it makes sense is a mould mark, secures the metal as it cools from the casting so the mould doesn't move.
