Hi guys. So, in the process of mocking stuff up and moving things around I ended up with a small scuff mark on one of the aluminum heads. It's not real deep or nasty, but you can feel it. It's between two cylinders. The heads have already been done, milled, etc, I had pushrods made, everything was ready for final install...At what point is it bad enough to have to go back to the shop? I'm using 8519 gaskets by the way, nothing fancy. Some copper on the spot be okay with the composite gasket? You can only just barely feel it, it looks a little worse in the picture then it actually is...thanks
