I have a Wheeler SBC intake manifold (simular to a Super Victor air-gap) that was on a used engine I bought. The overall casting is good, however, I had to do "a lot" of port-matching to get the intake ports to match-up with a FelPro 1206 gasket. The ports were undersize and some off-set, although, there was enough aluminum in the casting to match each port to the 1206 gasket.
After putting all that hard work into the port matching, I decided to run the Wheeler intake for awhile. I'm probably more proud of my port-matching then the intake its self, but would still rather have a Super Victor.
