Valve guide seals

[BANTAM38@xxxx]

I need some advise on replacing valve guide seals on my 258 6cyl in my 73 
Gremlin. The seals are shot and I get a big puff of blue smoke when I start 
up, otherwise it doesn't use oil.
I bought replacement umbrella seals, removed the valve cover, attached the 
cyl to an air compressor and used a valve spring compressor bar to compress 
the valve spring. I expected the stem to pop up and release the valve 
keepers, but all I managed to do was to open the valves with air blowing out 
the exhaust or carb. 
Is there a trick to an AMC engine I don't know about? Why can't I get the 
keepers off. What is the proper way to do this on an AMC 6?
