I am also in the process of doing head gaskets on my 380 sel after I converted to a dbl chain. When all is removed: heads, intake, front cover, and etc. there isn't much left. If I had to do this all over again, I would have pulled the engine/trans out together. This way, you might as well change the rear main seal and input seals of the trans. too. Iam elimninating my air pump and want to put tapered alum plugs w/ loctite into the holes that feed the exaust ports via the intake side of the heads. Anyone here done that by just tapping and putting bolts in? Or can you get these alum pins as a kit; I read about them in the cd manual. les
