S-Class Guru, M.B.DOC and and everyone else who chimed in, I just wanted to say thanks (for making this more difficult

). It would not be such a pain of a decision if I did not know any better to begin with, I have gone through and bought genuine parts, or ********AZ, and now that I found this sire I started buying through Fastlane, I never did the Super Parts-O-Rama stores but now this decision is a pain.
I am wondering that since the cam is as worn as it is (it seems the story's I read online never include cam and rocker replacement) that maybe the bottom end might be worse then I had thought (hoped). Between the cost of the new parts and the shops labor i am looking at $1,500 easily which is money for an older diesel to fix up.
The next thing is if it is worth it to that much into a car that I payed a little more then double that for and how much more am I willing to do (or spend) on this car. The trouble is that my Wife and I really like this one (especially my wife), the paint is decent (some chips here and there) the interior is great with the exception of the wood panel around the window controls and some idiot put a screw through the rear interior panel to hold it on. Is this car worth another paint job and dumping the money into it to basically overhaul (semi restore it)?
Last thing, If I could find a head or a complete engine I could always take the chance that the cam and rockers are good and make sure everything is disassembled and marked so it can back in the same as it came out and if I had the block to go with it I would have it on hand and ready to rebuild if the time came.
