Maybe you see it that way, but the water ports and intake ports are in the same basic location they have been in since 1955. Might be a little taller, wider, whatever, but if the gasket is big enough it will cover and seal. It is the bolt holes location, angle and number used that are majorly different and the thing that prevents swapping Vortec intakes for conventional intake.
