Hi Guys,

I picked up a non-running W201 with a swapped M104 from a C36 installed. The head gasket was supposedly blown when I got it, so I didn't pay much (thankfully)

A friend has just taken the head off and it's pretty clear that the gasket was bad. I'm about to send the head out for testing, but just ran the part number of the head to find out that it appears to be a head from a non-AMG M104!

I contacted my local MB dealer and was told that the part number should be HWA 104 016 02(maybe 01) 01 but the head I took off has R104 016 16 01 (yes, 'R' no 'A') The dealer ran this number and came up with nothing.

So it's looking like I got screwed. Are there any visual cues I can use to confirm this? I've done searchs on pics of a AMG M104 heads, but none of them are detailed enough to help me out.

I didn't pay much for the car, but enough that I don't want to just flush the money away.
