I'm going to calm everyone down about the welding process, but ONLY because it's a Packard block. I'm not sure how many know this but nearly all of the inline blocks are CAST STEEL, not the typical CAST IRON. It still takes the right rod to weld it and shouldn't be attempted by just anyone, but all of the re-machining slow cool pre-heat stuff is moot on these things. They also don't like hardened valve seats nor do they ever need them. A good tig welder could sweat that in with silicon bronze as well.
