Crazed Head of Cylinder Block info

I own 159 2.4 Jtd 2006. I am interested what is the material of cylinder head? What are valve seats made of? and what are the degrees of facet? Do they use this ceramic-metal material (powder metal technology or smth I am sorry I don't know how exactly it is in english)? What about valve guide material and the valve?
Moreover, maybe someone had written smth about 159 diesel cylinder head tuning here? Please share the links with me I failed to search
Thank you for any attention

I have not seen any details of the 16v or 20v cylinder head regarding porting polishing and 3 angle valve seat job.
On these turbo diesels the head is obviously not restrictive enough to be worth the expense of head work, when upping the boost is easier( to a certain point)
Not sure what your plans are , hp wise , but there are a few 2.4 20v near or over 300hp and ive not noticed any headwork being carried out, search likes of james f1 (i think), clogz , coxy in the tuning forum.
May have missed some other 20v tuners on here.
