Greg- I used this article & the accompanying pictures as a guideline for what I did. I was impressed with the results he got, with stock valves & some mild work. Basically just involves streaming the guide boss, blending the bowl to the valve job, & removing the pushrod hump on the intake. With heads & comp "268" cam, My '06 magnum picked up 8 tenths, & 7 mph. On street tires, stock converter & gears. I'll post pics of my hack job later when I get home.
