You would lose some benefit, but a lot of it is not there due to being at .059 already, IMHO. If you can, fix it right with setting the proper quench. Study what happened to the same motor when compression dropped from the factory back in the early 70s. That is a big clue as to what will happen to your motor. It all depends on what you want. Do you want it to run the best and spend the money, or do a quick fix and live with a motor that is down on torque? The other thing to consider is what cam you have. If it is bigger than stock, then reducing compression will be a double whammy. The motor will suffer even more loss, because your true compression will take a bigger hit. A total run down on what you are working with would help you get better responses also. There may be other options here, but we need facts to work with.
