Phorensic - an engine swap to a different manufacturer is a lot bigger deal than changing a head gasket!
You obviously haven't worked on a 3.0! It's a major undertaking to change the headgasket and requires special service tools. 185ft.lbs. of torque isn't pushing my 3200lb truck well either. Did some research lately and it's going to be easier to swap in a v8 than a 4.3. Broke the motor mount prerunning the MORE Barstow course so now that motor swap is looking more attractive.
