It's been a while but another little update on the re- re build of this SD-455 engine. The short block is now complete and I disassembled one head today to take a look. Everything is pretty dry in there but only a tiny bit of rust here and there. The heads are not ported or gasket matched. It has had a valve job and bronze guide liners installed and honed to fit. The guides are perfect. The original valves were reused and guides may have been cut for PC seals. Since I have never worked on a set, I don't know how they came from the factory. My plan is to lap the valves to get a visual look at the valve job, test the springs, upgrade to viton valve seals, clean and put them back together. The keepers were reused and in marginal condition. They will be replaced. Overall happy they don't look all hacked up inside. In the pics you will notice these heads have NO casting codes on the exhaust ports. Also no stampings on them anywhere. I looked carefully. No date code or day night shift. Only the part number, that's all. The connecting rods were "A" series forgings and I was told heads without any numbers were early castings?
