I haven't been back since the rocker problems because I'm moving cross country in a month. (it still made 581 that day). Probably a tick over 600 now, but will get it retuned @ vengeance on Georgia corn when I get to GA
Breathers weren't cutting it as it was still pushing the tiniest bit of oil at redline. It was fabbed valve covers with -10 lines to a tank, or a vacuum pump. The pump was only ~$100 more total then nice valve covers, lines, and a tank. Was a no brainer, since its worth a good bit of hp.
