This is the tool I use to check deck height with. You just put in on the cylinder with the indicator pointer on the piston and it will show how far down the piston is from the top.
Range: 0-3\", Graduation: .001\", Dial Reading: 0-100
I have two of these and need to sell one to help pay for more parts for my turbo motor.
This tool is in very good conditon and sell for about $200 or more new from a starrett distributor.
