I have been reading on other forums about fitting a 4lt head with injection on to a 258,

has anyone done this?
is it worth doing?

I know alot will say just get a V8, but cant see that hapening for a while and I want to make the CJ a true everyday car.

Yup, speak to Jim Wait. Not as simple as it sounds though.

i think its better to change the whole thing to a 4.0 not just the head

Nosebolt · « **Reply #4 on:** March 20, 2009, 10:20:18 AM »

that was going to be the next question,

what advantage is there to a head swap over a full engine swap or visa versa?

Not an answer to your question but loads to look at.

Also look at HESCO (google) have loads on heads from 4.0 to 4.2 as well as ridiculously spendy$$$$$ ali. head that ups the BHP..
Not for spending or getting unless you win the Euro-lottery tonight but interesting to read about.....

More Jeep Porn I guess!

Off top of head I think head bolt holes have to be enlarged to line up to 4.2 head bolts. So major machining .
