Im replacing the valve stem seals and i dont know how to remove the springs and with the valve compressor wont fit in the engine
Do NOT do what banit said, if you did his technique once you remove the keepers the valve would drop to the bottom of the cylinder and require a tear down. You must get the piston be at top dead center on the cylinder you intend on removing the valve springs from and you cannot do any other valves besides the ones on the cylinder you brought to top dead center. You can take the rocker arm off the top and take the push rod out then when at top dead center using a spring compressor you can take the keepers out, or if you do not have a spring compressor (proceed at your own risk) you can get an oversized socket and a dead blow hammer and place the socket over the top of the valve spring with the octagonal side towards the spring and give it a decent hit, but be aware the keepers will pop out and you may lose them if you are not careful.
you will need to remove the plugs, get a air compressor with a hose that will screw into the spark plug hole ! then you pump the compressor up to about 40 or 50 pounds, take the rockers off and pull the push rods ! you will need a spring compressor to squeeze the valve spring and take a pair of need nose pliers and take the keepers out and then the spring will lift off the valve stem ! after the spring is off you can remove the valve seal ! i recommend for you to use the umbrella type seals !
