The clip to the choke is stock, it helps heat up the choke as the car warms up. The valve cover won't get hot enough to melt the hose but the hose will rub a spot intothe valve cover removing the paint and making and indention into the vc, my original did this. Many people change carb/intake and route the hoses away since they don't use the choke clip and just want their intake area cleaner looking.
