Here’s the latest, I could never find a good replacement power head on EBay and I had some time on my hands so I ended up drilling / grinding out the broken head bolts and tapping the bolt holes for new threads. I was getting the head ready and to assemble, and I saw some custy residue in the water passages on the head. What causes this?
I cleaned this out while I was sanding the mating surface of the head, but I think the head was warped as it took forever to get the middle of the head surface to shine up when I was sanding its surface. Also, when I put the head on, do I put anything on the head bolts or head gasket , or do I assemble everything dry? Also, do I have to re-torque the head bolts after its first running, or is that for other engines?
