Noticed these marks when taking my head off the ek9. Just curious if anyone had any idea what they are?
There doesnt seem to be anything that would cause them?!lol

That's normal, it's just machining marks, no need to worry;)
 
As far as i'm aware they are casting marks cleaned down?
 
Yep, every head is like that, I think it's when the factory was tidying up the rough cast

Yep that's pretty much it, they just roughly gouge out the rough edges for clearance before machining the area where the valve spring sits and for machining the hole for the valve guides

Noticed mine are the same recently.
 
Quite a relief to read that it's something done at the factory, I knew there was no way any of the valve train could have caused it, but it doesn't look 'tidy' enough to be original.
