I have TFS heads & intake with Ford Motorsport 1.6 RR and the stock valve covers will not fit. The actually don't even come close. I just recently ordered a set of valve covers from Anderson Ford Motorsport that will clear them and they look nice if that's any help.
thanks, i guess imma just have to do some testing with the stock before i try these ford racing valve covers i bought so if the stocks work i can return the ford racing ones
