you were given bad information. i have the same heads you have. they do have two SQUARE humps at the front of the head. The double hump "camelback" Hi-Po heads have two small ROUNDED humps. If you need want more info on the heads you can pull the valve covers and get the casting #s.
FYI the 275HP 327 used the "camelback" heads, 4-barrel carb and different intake than the 210HP 327. Everthing else is same between the two though, cam, pistons, crank, etc. Fuel pump might be different too.
