Thanks for the heads up! Your right, the header bolts are black oxide (for now). LOL Jim at his little shop Mesa Color here in Durango is a friend and with that came the "Bro" deal so no warranty was offered or implied. If there was ever a problem with the work he did he would make it right. I wouldn't blame anyone but myself if I screwed the nice job he did with my poor choice of hardware. The valve cover bolts are SS, but that's just my rattle-can job on those.
