Im getting another quote from ALibaba 2nd year gold accredited
Ive dealt with other Gold Accredited dealers with success.

The chinese made heads have better quality casting, smooth
and improved kidney chambers.

Will need rocker gear from another country where this head was
sold as they dont sell complete heads.

NA20s were quite common here in NZ I think. Pretty sure my mates 1995 D21 navaara has one. He hates it. REckons its a pile of crap

you're right Nick they came in Navaras here in NZ. Not sure why D wants one, unless it is for a navara? Nissan put these motors in their utes (workhorses)and put four valve engines in anything even remotely high performance. To me that says something about them. Why not use a DE of some description?

If you guys come across 1 or 2 id really appreciate it as Im buying
the chinese cast blanks with better chambers but need the factory
head for the roller rockers and the rest if possible.

Any chance you guys can point me to a wreckers on your side of the ditch?

Chinese version, you can see the chambers are much better but I will get
a master welder to close up the chambers more into kidney shaped "8" some
bigger valves and some serious porting.

Reason those Navarras are nasty underpowered is cause you guys got the Na16s
and the NA20s which like the P version are stuck with horrible manifolding,
pollution gear galore, eco-torque only camshaft etc.
