The above pictures aren't mine. The vortecs can really use match porting. The below pictures are some match porting we did to mine over a year ago. You can clearly see where I redrilled the vortec heads for use with my syclone intake.
















Here's a pic of my engine bay with the vortec heads installed. You can't even tell unless you really know what to look for. I drive the truck almost every day.
