In 1966 did the Corvette 327 come with dome top pistons and or double hump heads?

I have a 66 327 block with a steel crank and some non-double hump (non-corvette?) heads. The block does have dome top pistons, yet i'm not sure if they were original to this motor. I imagine it could have come with either the DT pistons or the DH heads, yet not both?
