camshaft replacement in 4.0

92 wrangler yj w/4.0 HO

alright guys at some point soon i'm putting a hotcam in the jeep. i'm getting a crane, one thats less aggresive and is not supposed to cause problems with the computer/fuel injection system. Basically i'm looking for tips, instructions, possible problems with the camshaft swap in the 4.0. i'll be replacing the valve springs as well as the lifters so i guess that means im pullin the head. i of course know to keep track of the cam and distributor position and timing. i do know what im doing in general, i've pulled heads on other cars, but i was wondering if there was anything "special" to the 4.0 i need to know about. or if ya got some instructions and time to write them it sure wont hurt anything. thanks!

this is from the FAQ, but not too detailed:
