Okay so using this head is obviously out the window. In terms of getting a pair of heads rather than just one, that's where my dilemma begins. I've been working on this Montero for the past year and had the heads cleaned and rebuilt several months ago. About 2 weeks ago I got the bugger running and drove it around for about 2 hours total. Then the cam seized. So trying to find another pair, when I know one of the heads is in optimal shape, is the kicker. If I can get just one head, rebuild it, and have the piece of mind that it'll run just as good as having a pair from the same vehicle, then I'll probably just do that.
