Cylinder Head Compatability

Just discovered that my head on my 1983 CJ-7 4.2L is cracked. I was wondering if it is compatible with a 4.2L head out of a 1989 Wrangler.

Thanks,
Ryan

No it isn't 100% compatible. Your CJ uses 7/16" head bolts (only on 81-85 258s) and the YJ head bolts are 1/2". It could be used with spacers though. Summit Racing has the spacers, which are the same ones used with 4.0 head conversions.

I looked on summit racing and couldn't find the part, do you possibly have a link or part number.

Thanks

Here is another question for you, what if I could find one in the junk yard out of a cherokee the same year model as my CJ. It should be the same right. I really don't feel like messing with the spacers, but I'm moving a less than a month so I need to get something going quick.

an xj cherokee was not out at that time, if i remember right. if it was, it was a chevy v6 and not an I6.

a full size cherokee would have had the same engine, i would imagine though. if you can find an I6 powered full size cherokee or wagoneer

I actually found a 1983 4.2L engine (everything) for $300 but for that price I can get a re manufactured on 4wd

I ended up going with the re-manufactured one from AKC. It actually turns out that Advance Auto carries the same head as 4wd and they matched the price plus the shipping cost ($30). So after tax it cost $300.32. I priced out fixing up one of the other ones I found locally and it would have cost about $50 for the bushings and the $100 for the machine work and probably $50 for the head, so for an extra $100 I was able to get piece of mind and a warranty.
