Well, the head gasket was blown just across water jacket and oil jacket.. not bad at all, but just enough to see some milky color oil. I pulled out my machinist square and checked for straightness on the block, its pristine.. It was supposedly a "low" mileage JDM motor.. and well so far it looks to really only have maybe 30-50k on it, I mic'd the cylinder walls, the bores are perfect, the cam journals are beautiful, no scouring whatsoever. I was looking at my old head from a turbo motor I was rebuilding until I discovered rod knock and a spun bearing. I had the head decked with a ground mirror finish, and leak down tested. there is a little bit of oxidation on the cams, but I am going to just swap all my stuff from the NA head, to my old turbo head. I know some of you advised against this, but on my inspection of it today, It all looks really good. So I think I will go ahead and just drop my HKS 1.2mm HG and ARP studs onto this build instead of the Ajusa.. I will keep it for later.
