Re-routing the radiator hose and break fluid reservoir is no big deal, the biggest problem i found is the heat generated from the headers. I.e. Idling for about 2 mins melted the radiator fastening rubbers and any longer, the header would have glowed. With all that soft rubber and plastic around that area, not to mention the clutch cable running very close, I just never had the confidence it would not melt something. I did not however exhaustively look into the heat shield option but I cannot see anything as thin as tape shielding that much heat...
