no. neither of those have an integrated headset. the mark v has a threadless headset, that generally would save you a bit of weight (not on the frame, but on the complete build due to a lighter stem). the angus has a threaded headset, but also uses better tubing which is why the frame is lighter.
an integrated headset saves you like 10 grams over a non-integrated headset.
edit: beat to it.
