are these cuts factory or custom ?

first off its a h22a4

had this pic for a while so its a bit old, but i took a pic when i was painting my valve cover and i saw these "shavings" ( i would say ) and just always wondered



i remember a while back when my uncle had bought the motor swapped in, it was sitting for a long time in a garage so he knows it has much less then 40k on it , and
before that a friend of his rebuilt the motor ( i really doubt that it was rebuilt for modification, but more of maintenance thing and i assume it was a brief rebuilt ) and
finally before that it was in a 01' prelude that a kid wrecked street racing ...

thats really all i know about the history about the motor, so who knows

i am not much of a motor freak when it comes to the internals, but to me it doesn't look factory

is it only on that cylinder and those 2 valves?

on all the cylinders slightly cut differently

do you have a pic from the top without the red arrows?

i believe they are factory to accommodate the valve lash tool.

i think so too, but he said they are cut slightly different. honda would cut them the same unless there was something underneath or to the side that they did not want to take away from or get close to. there are factory cuts right there i think its for machining purposes as well as possibly the above mentioned reason. but that also does not mean somebody didn't make them larger or modify them, for what reason i have no idea, but i have seen worse.
