I Know some people, and their son['s] would not approve, but, to know how much to mill off the decks for the height we wanted, we measured how far in the hole one of the stock pistons was, we then pressed it off the rod, and measured the difference between the stock piston and one of the new piston's pin height. We then then did the simple math to set up on the 570. Believe it or not, it came out right. Crude, huh?
