I picked up some umbrella comp cam seals for my about 1980 350 chevy. The pulley type spring compressor was of junk replace one valve seal but when we tried to do the other the spring would not slide down the valve to be able to release the keepers. the first on the seal was like stone and would let us slide the spring off after getting the keeper off. the intake on #1 was worse and when we tried to slide the compressed spring down the valve would just open against the air pressure. Not going to attempt it till I have a better compressor . But any suggestions to getting the spring down with those baked on seals that are on there. Thanks ED
