This is actually a split port...but barely. It doesn't have the long runners like the SVT one...and the "runners" are barely existant in the UIM. But the TB opeing is the same as the full oval port manifold. but te heads I am using are oval.
The IC I had almost fit. I just had a guy re weld th inlet and outlets. I did all the cutting and marking, etc. then he welded it how I had it set-up.
