These plugs have been in for a while. The truck has 120K miles on which isn't bad for a 1988 Toyota. I don't think they are cross-threaded, just a lack of anti-sieze may have gummed up the threads. Steel spark plugs in aluminum heads. They might be the original plugs as they are Denso plugs in it and most people don't bother to put them in.
