Anybody with a 4.2 that's done the 4.0 head swap plug their antifreeze ports with packing peanuts? Ordered some on Amazon, they do dissolve in boiling water but left a little film, wondering if that's normal/something to worry about. Don't want to go through all this trouble to have them ruin my water pump or something. Thanks guys, this forum has already been so much help. You guys are all fantastic.
