Default Engine help needed

Here is the deal, Im great at tuning an engine and can get everything it has to offer and can do mild mods. I just came home from a race series that I usually do very well in with a 3rd place finish. Even after that disappointing finish I am the points leader in the series but the guys are nipping at my heels. Bottom line is I need more power but have taken the engine to the limit of my knowledge. What I think I want to do next is extend the exhaust and intake duration. Exhaust I have done some and it,s at close to 140 degrees. My biggest question is the intake. Do I want it to open earlier or close later? Here are the particulars:

Rossi .45 VP, 10mm carb, Ultra thrust muffler, 15% nitro. Currently spins an APC 8.75X 7.5 at 17K. Any help is appreciated
