Nothing looks meaner in a '69 Z/28 like the original cross-ram intake. While Warren does own a few original intakes, he opted to use an aftermarket re-pop for this build. In order to use the cross-ram with the AFR heads, a fair amount of work had to go into the shaping and port matching of the intake. The ports had to be moved a little up and over for a proper fit--you can see the groove milled down the side of the intake. Without this groove the intake will not fit onto the AFR heads and the valve covers will not fit either.
