[Vwdiesel] Valve adjustment - 1.6NA

Yesterday I received my Ebay surprise - a box of about 80 discs, and the 
two valve adjusting tools for mechanical heads. Kind of ironic, but they 
actually were sitting on my front porch the whole time I had my injectors 
out & was working on new glow plug wiring... and thinking wouldn't it be 
nice to do the valves at the same time. I guess UPS dropped them off 
while I was out.
Anyway, I spent a few minutes sorting through the box, and found I have 
at least two of each size from 3.00 to 4.25, so I'm all set. I have nice 
looking Hazet pliers for extracting the discs, and the 546 tool for pressing 
the followers down. It appears like the lever inserts between the two 
buckets and depresses both valves at once - is this correct? Any other 
tricks I should know about?

ps: While I had my injectors out, I did a hot compression test (injector off 
for about 10 minutes after long drive), and found an interesting result: the 
low & high cylinders had swapped: I now had 450-380-390-430 hot, 
whereas before, dead cold, I had: 390-430-450-350.
I'm wondering if the difference in valve clearances between hot & cold 
could account for such a shift? I'll make a note of clearances (hot) before I 
adjust the valves and see if there is a correlation. Or it could be that my 
measuring technique is flawed...
