Keep in mind this is only a mild PnP. I really just wanted to finally figure out how to post images, but here ya go.
You need 200-300 , Wet Sandable 800-1000 and 1500 Grit Sand Paper. Something to use to scrape some of the major build-up areas. Carbon-Cleaner (You dont really need it but it helps alot). Of course all the tools needed to get the Header off.
First port done. The one on the left is finished. The one on the right had a some of the first stage of sanding.
Started on the second port. Needs to be polished still but thats after the last stage of wet sanding.
Two more exhaust ports to go. This is turning out to be hard as with big hands your knuckles hit the exhaust manifold bolts/studs.
Pretty much done here , just a few things to touch up and on goes everything. I also sprayed some carbon cleaner in there.
Walla, put your header back on and enjoy.
