Chad..2 very good questions! Would the performance gain be worth the $$$$???

I`m having it done on my home ported rpm`s and Pettis and a few others think it is worth the $$$ as long as the rest of the port can support it. If I get 8-10 cfm(16-20 hp),I`ll be good with that cos I need every hp I can get to get my 9.78 timeslip.
