This is a doable job for the shade tree mechanic. What year truck?
No, the cab does not have to be removed.
If you don't want to pull the engine, you can replace the cylinder head/ gasket while it is in the truck.
The head bolts are TTY - torque to yield, which means that they can only be used once and then must be replaced.
The interference locations are at the back of the cylinder heads just under the firewall. So, the new rear bolts must be placed in the cyl head before the head is installed, two (?) or three per side IIRC. This can be done by putting the bolts in the head and holding them in place with large rubber bands so that the threaded end of the bolt is just above the surface of the new gasket when going on.
I would suggest pulling the front wheels off to lower the truck, and removing the plastic inner wheel wells for access.
