Mud friends- I am in the middle of a HG job and have come across something that I would like feedback on. It seems to be a minor imperfection on the block surface. I have included a photo in which this small area is circled. It is a "groove" (I call it that for lack of a better term) that just barely catches my fingernail when I rub across it with pressure. The hole that it is above is the furthest to the driver's side, cylinder 6 as seen in the 2nd photo. I have had two friends here look at it and neither think that it should be an issue. I am posting here to get the most educated opinions that are available regarding the 1FZ. I am hoping that my lack of experience with this is just making me paranoid. I have a new OEM gasket and head bolts to put everything back together with. Thanks for looking!
