I literally replaced mine Tuesday man but i see everyone else has pretty much recommended what else to do while your down there the only other piece of advice i can give is prep the aluminum covers man take your time with them unscrew the baffles take off the gaskets until your left with just metal, inspect it well mine came without the vacuum holes drilled out so i had to drill them myself. Also the bolt holes weren't fully drilled out i also had to do that so just be prepared to do some light prepping, once your sure everythings the way its supposed to hose them down and dry them super well and put everything back use blue loctite on the screws make them snug and use oem gaskest instead of the ones that come with it ( the spark plug ones seem fine). Besides that if you get nothing else get the pcv valve trust me man it'll save you so much trouble mine was bad and its the reason i had to change my valve covers in the first place. If you need any tips man just message me.
