Okay, here's the deal. It's made cheaply in China, so: If you already bought it, you'll want to use a Dremmel and smooth out the runners and port match them to the heads.

If you didn't buy it yet, look for a used intake in the classifieds here...Go w/ the Edelbrock RPM/RPM2 or a Trickflow Street/Track heat.
