thanks for all answers
asap I will send picts of my intake.
the only 3.0l in europe is the new mondeo ST220 and maybe the jaguar but it is only new and very expensive and as I am flying 747 jumbo to sfo and lax then tahiti, I spent time in ca evry month and I think I am going to search a 3.0l there.
if I understand the 2001+ 3.0l with its head is good for water but not for lower intake (I have to re-built something) and is less powerfull than with 2.5l heads because of lower compression and with 3.0l 2001+ heads I can still use my msds headers.
Do you knom a dealer for hc pistons for a 2001+ 3.0l to have the same compression than the 3.0l with 2.5l heads?
and last for you, what is the best engine :
-3.0l with 3.0l 2001+ heads
-same as above with hc pistons
-3.0l with 2.5l heads

(I can keep my special intake with the 2.5l heads and post 2001 3.0l heads or rebuilt a new one for 2001+ heads, in my airline they have plenty of tools and materials and as I am living close to Bordeaux I can give them some wine and you know french : for some wine they can do miracles)

thanks for all yourhelp
