Yeah that is what my Victor heads looked like too. It appears that the designer at Edelbrock just used the wrong dimensions on the Victor valve cover rail. I would assume that whoever designed the Victor head would just re-use the dimensions from the RPM head but evidently he decided to create a new design which doesn't fit any known gaskets or valve cover. Beats the heck out of me! That was one of the reasons why I decided not to run the Victor heads on my engine.
