MuddFoot Posted May 9, 2014 Posted May 9, 2014 i have a extra head i keep laying around just incase i need one. my uncle has a 96 jeep cherokee 4.0 can i use my 89 head on his? if so do i just get the gasket set for his year or the 89? everything looks to be about the same but little change in the intake ports.
JeepcoMJ Posted May 9, 2014 Posted May 9, 2014 No. Not without hours of porting work. You need a head from 91 and up If your putting the 96 block in an 87 to 90, and keeping the renix manifolds and injection, then yes you can do so. Cams are different on renix (87 to 90) than high output and do put out better low end torque
MuddFoot Posted May 9, 2014 Author Posted May 9, 2014 wow that sucks now i have to hunt down a head for his jeep. Thats gonna ruin his day
JeepcoMJ Posted May 9, 2014 Posted May 9, 2014 Not a big deal. Buy one from a 91 to 96. don't get a 99 to 02
sinkrun Posted May 9, 2014 Posted May 9, 2014 Wish you were closer I would trade you a 89 head for that 96.
sinkrun Posted May 9, 2014 Posted May 9, 2014 Sorry I read this wrong and in a hurry. I need a 96 head I have a extra 89 lust like you do.
JeepcoMJ Posted May 9, 2014 Posted May 9, 2014 Remember, you need new valve seals as well as to lap in the valves, check springs and retainers as well as for bent or worn rockers, and now is the time to check out lifters and push rods. How is it that this 96 head has gone bad.
JeepcoMJ Posted May 9, 2014 Posted May 9, 2014 Pay to have it cleaned, lapped, new valve, new valve seats, and resy to go. You are NOT going to be able to just buy a head and drop it on. If it's off, it gets rebuilt. No exceptions to this unless you like doing work twice.
MuddFoot Posted May 10, 2014 Author Posted May 10, 2014 thats why i wanted to use my extra i had it machined like 2 years ago. just been sittin
JeepcoMJ Posted May 10, 2014 Posted May 10, 2014 The best priced one i find on ebay is $300 for a rebuilt one. That would be the way I would go, $300 and it arrives on your doorstep ready to install.
MuddFoot Posted May 10, 2014 Author Posted May 10, 2014 i think 400 for a used motor from my buddys junkyard sounds better and its only 120 to get a head redone here just don't have the time to wait for it to get done
