well ive been running my pac1218s for a couple years now w/ my XER lobe cam and figure i better go ahead and change them out. just looking for opinions on weather i should swap some more pacs in there or if i should upgrade to some pat golds w/ tit retainers. thanks also wondering if anyone knows who make the summit brand rockers for them or has any experience w/ them. also has anyone had comp upgrade the stock rockers for them and how they like them. thanks guys. mark
