All you need is a new head gasket , base gasket and cam chain tensioner gasket. Most people say don't do it unless you have a aftermarket cam but you already have one so go for it. I will be doing the same piston upgrade very soon , but mine will be thermal coated. The reason i know what you need for the install is because i recently asked C&D Racing what i would need and that's what they told me and he also said that i could get away with running 93 pump gas but they recommend atleast 50/50 mix with 93 and race gas. Im going to run 50/50 just to be safe. They also said that there is a huge power increase all through low-mid-top but im sure you already know most of this stuff. I will have mine installed within 2 weeks and will also be switching my slip-on pipe for a full system which is also recommended. I can't wait!
