Drain the coolant properly before and when you take off the head take some pics. You want to see where it was leaking from the coolant jacket into the bore. Also look for the root cause, head gaskets don’t usually blow unless there are overheating issues, or (in my case) misfire problems…
Buy a price of plate glass10mm x 30cm x30cm to lap the head clean and smooth…
Don’t buy a shitty head gasket, get an Athena, Vertex or genuine head gasket…
