Minimal at best! I would NOT hog out a set of manifolds. Not worth the effort. An open scoop, RAIII manifolds, a cam (not 068), and good exhaust can make a huge difference. The 068 cam has no lift and really is geared toward a higher compression ratio. There are much better choices for cylinder filling and the 8.1 CR that you will have.
