update for anyone interested....we didn't do it. We looked at it, and stared at it, and we were both SURE that it is exactly right. then the boss remembered he has a friend who's a master mechanic. so he's coming by on sunday and we're all going to get a quick course in engine repair, followed by the putting together of the car. (which I am hoping to post pictures of soon, except for the color (lexus grey, don't ask me why) it looks like a brand new 70 z28. so anyway, I'll post sunday and let you know if we screwed it up horribly, or just badly.
