I recently did mine. Its a real pain in the a$$. The headbolt under the brake booster is impossible to torque. Do not remove the center timing chain. Make sure you check your chain guides(PLASTIC) and tensioners as these are prone to breaking and sticking respectively. The gasket between your chain cover and the block is $70....replace it. Replace your waterpump gasket too. Make sure you set everything up at top dead center BEFORE you tear it down and try not to rotate the motor when you are pulling the front pulley. Also, there is a special puller for the front pulley. Autozones loaner tool program is the $hit, tell them you need the pulley puller for late model Dodges.. You might as well change your plugs, oil, filter, thermostat while you are at it as you will get a little water in the crank case when you pull the heads off the block. Take the whole head with cams and lash adjusters/ rockers to a good machine shop to be resurfaced. Have the valve stem seals replaced and let them reinstall the cams and stuff. Its much easier that way. Check your fan clutch since it will be off and replace it if necessary. Consider replacing your water pump too. Just a little extra insurance. I was getting a huge amount of water in cylinder # 1 and 3 in my 2000 Durango. Good luck and have lots of gause on hand as you will bust a couple of knuckles!!
