Subject: V8 head removal|
Hi, I'm looking for some information on removing the heads on my 2000 Dakota, it's got the 4.7 L Magnum.

I have a 2000 club cab dakota, 4.7 5speed stick,
I bought the chiltons manual for the dodge truckes which has a good engine overhaul section in it, lists the 4.7 with step by step procedures

I had a head gasket go on my 4.7 last March. I decided to change them myself.
I will say, the 4.7 is a great engine to work on. It's really a pretty straight forward job to pull the heads. Just a lot of other stuff to pull first.
Gotta remove all the stuff on the top of the engine first.
The trickiest part is the timing chains. In the manual it says to remove the water pump, etc... and actually remove the chains. I didn't do this. I took a piece of wood and inserted it between the chains in the same place you would when changing the cams. Then, I took some cable ties and pinched the upper ends together onto the wood, so the chains couldn't move. After unbolting the runners the chains are in, I carefully removed the heads.
While I had them off, I had them milled .020. I also polished the combustion chambers, and opened up the ports a bit.
The only part of the job I didn't do myself was the actual setting on of the heads. I had someone help guide the chain-guides back into the heads, stuck the bolts in, and removed the cable ties. Then, just bolt the whole thing back together.
I must say, overall it wasn't hard to do, just time consuming. Took me about 5-6 hours just to put everything back together.
Also, considering I had over 100,000 miles on the engine at the time, I was amazed at just how clean it was inside. After all the posts on this board about the 4.7 being a sludge motor, I had absolutely NONE inside my engine.
I wouldn't hesitate to rip into it again if I had to. However, I just ordered a new 1500 4x4 Hemi, so that's not gonna happen.
I'll look around and see if I still have any of the pics I took. I found a digital camera really helpful, just snapping pics of where hoses, etc... were before removal
