im running blox b on my dc2. i was happy with them for a while but then as you continue driving etc you get a bit over them if you know what i mean and as far as my research goes on them theyre only slightly bigger than type r cams. dont bother with them imo as i am now upgrading to toda c2s because they suit my hi comp build much better. in saying that my mate has made 154kw on an 11:1 comp b20 with blox b cams. 600$ wont get you much in regards to parts etc. there is little to no point in doing cams if your not gonna go the full hog and port and polish the chambers, change springs over, retainers, throttle bodies and manifolds. PM if you need any help with anything
