[QUOTE="ford20, post: 14537621, member: 140884"] Today was a productive day all things considering. First I started off with removing the heads. It was a fairly simple process, nothing really all that major to report there. Upon first inspection I didn’t see any signs of a head gasket leak, nor did I see anything that would indicate detonation. Just a whole lot of carbon buildup for 18,000 miles, well at least in my opinion. Here is the LH side Heads along with a close up of the piston heads.
