the Viper valve cover is made of magnesium,you cannot chrome it as it will for lack of a better term MELT,you can polish them, unfortunately it will soon oxidize,so basicly there are three solutions,1- design a new one. 2-leave it alone,3- what we have done,make a mirrored polished stainless steal overlay lazer cut to perfection,not to mention a grrrrrreat deal,now for the intake,if you can find someone to plate it let me know i have sent them to the best in the buisiness(california chrome)cant be done, at least where it would last or not take a chance of getting copper,brass or chrome into the runners and introducing them to your cylinders(not a good thing)however we do have them mirror finished polished and coat them with a special clear that does not take away from shine,have put them on many cars including many on this board,no special polishes just wipe it off wala no maintenence
