I was attempting to remove the cylinder heads on my 4.0 donor motor which I am still deciding what to do with. Thought I would open it all up and see what condition it's in. When I got to the heads though - I couldn't get the first bolt out. I have so far broken three sockets! Just ordered a snap on - but was wondering what is the best method to get these bolts out? Impact wrench? Heat? Hammer? The manual suggests a pretty low torque value - starts at 15 lbs and then two 90º turns - so they must just be stuck.
The manual also mentions "lifting eye to cylinder head bolts - 30 lbs." What is that referencing?
Cylinder head - remove
