Okay, from what I understand the M54 head is identical to the M52tu head. Is that correct? I have searched and searched but I cannot seem to find a thread or post with anyone actually saying that they have placed an M54 head on to an M52tu block. I have read several people say that they 'think' it is possible or that they 'think' the heads are identical. Does anyone know for certain before I spend my money? Perhaps I am being overly cautious but I just want some verification from someone more experienced than myself before I start handing out cash.
Same part number for the head comes up for M52TU and M54

Valve dimensions are the same, so there shouldn't be interference at the very least. Probably just a materials change or something
Well, I have my the head off of my M52TU and will be reinstalling an M54 head this week some time. I went ahead an ordered the M54 head Friday and it somehow arrived on my doorstep less than 24 hours later. While it may not be relevant to anyone right now, maybe this thread will pop up in the future for those who have the same question. Anyways, I will have a definitive "yes" or "no" for this question soon enough.
So,any updates?I want to put m54b30 head on my m52b25tu.Is it gonna happen?
Why are you replacing the head and why not use the correct part
