hi yes your valves will have had contact depending on the revs of the engine usually between 6 valves to all 16 valves
i repair renaults all day long and often find it a lot cheaper to buy a head off a scrap car £50 to £120 + tensioner £30 +head gasket £15 from uero parts at the most £165 no need for head skim as its come of a cold running engin probebly done over 6o cars this way never had one comeback ps allways check for intact cam belt on scrap car and clean oil on cams
