What does this mean opposed to regular timing? I set it to 0degrees at idle and made sure that it advances with throttle. At first it didn't, which I discovered was due to the vacuum advance tubing being not correctly hooked up

This is what I did, just backwards. I screwed it all the way in, and backed it out until it ran smooth, then reset the timing. Drove around the block a few times making small adjustments until if was smoothly.

Is this what you would call a "valve job"? Where you remove the rocker cover and adjust the clearances? I was going to do this over the weekend if I got my hands on the specs.

You want to check advance versus engine speed. Time to download and read the workshop manual.... The manual gives the specs. If it is not within spec, have a look at the centrifugal advance and see if something is broken.

Not what I would call a "valve job". In my mind, that mean pulling the head and lapping the valves. Really just get the proper manual, and follow the instructions.

As they say nine out of ten Land Rovers are still on the road. The tenth one actually made it home...
