Going to look at a 5mge engine for sale next week. The owner has a list of all the machine work done to it and the head. It's un-assembled so I can see the pistons. The pistons are supposed to be $600+ but I really don't know how to tell if they are special or not. So, any pics would be nice so I can educate myself before making the trip. Hope to buy this thing along with a few other parts. It's hours away so I have to make my decision once I get there.
