My friend, a nissan master tech has a set of heads from a 2K3. what performance improvements could I make to them if I wanted to install them on my car?

I also posted this message on the advanced Performance/All motor section of the org

Thanks,

Trex

 

does anyone know what these heads are worth? Not what Nissan would rip you off for them, but what would be a good price to pay for them.

Thanks,

Trex

 

You have an 02, the 03 heads are the same. Unless you mean from the '04. A34 chassis.

That case I don't know.
