Block says D15B2. Head cast code says PM3-18. No info about PM3-18 whatsoever on the web other than someone saying their a6 head said PM3-18. 16 valve no vtec and mpfi swapped. Just need help finding out what it is so i can figure out what tuning needs done.

Heres the head if the link works:
Head with cover off

 

What do you mean by tuning the head? Thinking of installing a different cam or just wanting to do a valve clearance check? Looks similar to a a6 so could just use the same oem specs for clearance if that's your intention..

 

Yeah just want to know exact specs so i dont accidently put in the same parts
