lol well seeing as the manifolds are made out of Nylon.. or a plastic basically. They cant be polished. And porting them would be very difficult due to the material as well. Thats why there aren't many responses. I would also think the V8 bolt on section would be a better spot for this too mayb. Good luck with results.
