Ed, some of wehat you're experiencing might be normal for racing duty useage. I could be wrong. you might consider one of those evacuation hose and tube setups goin into the header from the valve cover.
that kind of what i was thinking but like said its only good for top end... maybe after they fix the guides (exh)... again it will chill out... doubt it tho...
easy thing would be a vacuum pump but i cant even afford axles right now...
