CH='s measured distance from pin hole edge to the piston top + (half of the pin hole diameter)
We checked that at the shop today, well one of my guys did.....does 1.561 make sense? I had called summit to confirm before ordering that they werntn "rebuilder" slugs at 1.540 and was assured they wernt. I suspect I'm just off a tad andc they are actually 1.560..!!
