Well, what do you call an eight-card suit? Especially one as solid as North's. Playing in clubs, North doesn't need good hearts opposite, just the top controls.
4H on the 2nd or 3rd rounds is a practical bid by N, but he should spot that this might get to the wrong slam if South has extras. Better would be 2S followed by 4C or something similar to show a club slam try - you can still stop in 4H. Once North is insisting on clubs, South should realise he has a very suitable hand (lots of cover cards, nothing wasted).
Also could South consider 2NT over 2S? (since 2S is GF, this should show a spade stop and probably extras too (PFA)) So the full auction would be 1C-(1S)-2H; 2S-2NT; 3C-3D; 4C-4S (cue). Now North can risk 4NT as if partner has two keycards then North passes the 5H response. After 5D (0 or 3) North bids 6C, or possibly 6NT, counting twelve winners (SAK, HAK, DA and 7xC).
