I noticed the cylinder heads had some rust in the intake runners, so I figured I’d bust them off and clean them up a bit. I’m glad I did because a couple of the intake ports had some pretty nasty rust scale. A little elbow grease and a wire wheel and all was good in the world. It was also a good time to do a good ol’ redneck valve job (i.e., old fashioned backyard valve lapping). The heads turned out nice. They held mineral spirits without leaking, so hopefully they work.
