Scott, I bought the same tool. It got the stock ones off the head, during my extended, expensive, head porting, ordeal. It took all I had to get the 60 pounders out of the head. I had the luxury of being able to use the old C style and used it on the install. Nice going on the modification of that silly compressor. I also had a hell of a time with the cam action. Had one spring fly off and spent a half a hour finding the keepers.
