Did GM make a non-vortec center bolt head?

Ok- I just got in a lengthy argument with an employee of a local performance part shop. I told him about how I modified my non-vortec intake to work with my 1.94/1.5 Vortec heads. He told me that the only difference was the bolt angles- and said there was nothing wrong with my set-up. After that, he proceeded to tell me that Vortec heads ONLY have 8 bolts, and all of the bolts are perpendicular(He showed me an intake like this, and its certainly not what mine looks like). I told him that I knew mine were vortec's
[I know they are vortecs. I assembled them myself- and my mechanic friend gave me a big lesson on what makes a vortec head a vortec head- showing me the differences. We honed the bowls in his shop].

He said that my heads arent vortec, and they are just an early Center-bolt style stock GM head.

Am I totally wrong here? Did I get ripped off when I bought my heads? This guy totally confused me!
