There are a lot of normals that have head markings. I have a proven breeder normal that has a weird head marking but she's still a normal.
Additionally, normals come in a lot of shades and patterns. For example, here is one of my normals that I think is super pretty. She's really light and has nice banding and a head marking, but she's nothing special.
I've also seen a lot of fires for sale that look more like normals to me. Fires are one of those morphs that just get better with age. My girl was bought as a male and she was still the nicest fire I saw at the show.
It's rare to luck out and buy a normal and have it turn out to be something else, but depending on the seller you will find some hets sold as normals.
