I have no data on mine before and after, but I bullnosed the top of the plenum divider on mine then put a bigger radius on the transition from plenum to runner on my RPM.  Pretty easy work on some, some required long burrs and some hand work.

We just tried it on my 416 that Jay dyno'd. My motor is pretty high strung but it did not really help. My best numbers were with a 1 inch open and a 4 hole on top of that. The Super sucker sure didn't hurt but for 125.00 bucks it didn't make much difference. One thing to note aslo was my center divider is cut down 1/2 inch and the plenum area is worked some. Like Barry said, every combination reacts differently to spacers. There is no cut and dried rule. It sure wouldn't hurt you. It just didn't make much difference on my combo. Jim
