At this point I have 3 sets of 1.5 roller rockers. 2 comp cams sets and one chinesium set. So I'll probably save the dough and stick with the other comp cam set. And leave the other comp set in the current 410 for the duster. I'm really not sure which heads to get, I've had good success with the cheapo soeedmasters and could alwaysport them myself again. But I kinda want a CNC set of heads so everything is uniform.
