ahh, yes. you make good points. what I am doing is taking the head from a '95 jeep grand cherkee 4.0L that I found in the yard and unbolting the head from the block while leaving the intake and exhaust manifolds attached, along with the thermostat housing, fuel rail and all the sensors and vacuum lines. then, i'll try to reconnect everything. it doesn't sound like too big of a headache and its only gonna cost $75 from the wrecking yard. then I got the fuel injectors from a '95 JGC 5.2L, which flow better at the same psi. after I port the heads myself and finish the intake and maybe put the 62mm throttle body on, she should be a screamer (on the stock side of screaming that is) thanks guys

Not quite. The throttle bodies are different. The Renix throttle body will not bolt right onto the HO intake manifold. oh yeah, thank you. I was going to use the HO throttle body too and hope the new sensors will match up with the plugs.

ahh. nice thank you. so if i get the HO intake and exhaust manifolds it should just be a bolt on deal. thanks for the knowledge!

i have an 89 mj 4.0. i want to put on a 1995 HO head but am unsure of the things that won't fit. for instance, will the coolant holes line up? will the renix mpi and intake match up? any help would be appreciated. thank you
