i have never seen the engine in question, but here is what i did to get them out of a motorbike engine once, please ignore if it isn't relavant.
take a sliding g-clamp thing
find a short piece of tube that will fit nicely onto the valve spring retainer, and will fit in the bucket hole easily
weld a piece of steel on either side and one across the top.
______ <--- steel bits
| |
| |
| |
------
| | <---- small tubey bit
------
then place the tube on the valve retainer (take bucket off, if the 7m has buckets. which i think it does) slide the clamp down on it, then crank it until you compress the spring. remoce collets with little pointy nosed pliers.
hope this isn't too off track, it seems liek something you might have already thought of.

nah mate. worked fine... i get what you mean. was was trying basically the same thing but with a fixed srew type G-clamp. might try the sliding one thou...youve given me an idea.
the problem w/ the 7m is that the springs arent exposed, thyre recessed into the head with the nice shim arrangemt sittin flush on top of it all. when you compress the spring, it dissappears into the head, and i cant get to the spring retainer doodads sitting on top of the valve stem. its all too fiddly/tight.
still, youve given me an idea.....
cheers

you have to apply pressure to the valve too, then the collets won't go down into the head. the motorbike engine was bucket+shim too, so should work. glad i have given you an idea, just don't push the vale down with the spring and retainer, you want it to stay shut.

Is the head still on the car?
If the head is off of the car, you can put a rag under the valves,(ie combustion chamber)
Get a 5/8 spark plug socket put a magnet inside,
put the socket on the upper spring retainer and either
a. push on the socket with your hand
or
b. tap the socket(in line with the direction of movement of the valve) with a hammer.
This way can be very quick.
note: the retainers will occasionally go flying. If this happens, make sure you see where it lands.
note#2: No matter what method you use, please take care not to scratch the inside of the lifter bores. If this happens, the bucket may stick in the down position, causing no compression.
To reassemble, use a socket similar but with a big window cut in the side(s) of it. If you have a helper to push while you fit the keepers, you will be less frustrated.
A socket with 'no windows' is used in the first part to reduce flying keepers.
