I see no point, it can never be as good as the adjustable aluminum piston.... As discussed earlier in the thread, it will end up between the stock piston and the aluminum cup piston, depending on how good a job you do.... If you do a good job, up to 10 pumps, your results will be so close to an F-T-P that it won't matter, and vastly superior to a stock piston, IMO....Bob
