I would not suggest a reground cam in a Mercedes. They have been regrinding cams for years for American engines and then burying them in the middle of the engine. I tried the regrind route years ago and found them to be extremely noisy in overhead cam applications. There was some Mfg. probles with the early 4.5 cams that caused the right bank to go South. The replacement cams never had a problem. I would go for a good used unit. I may even have one kicking around I could sell. I know I have a have a set of heads with the valve job done.
