i dont think many builds have zero deck height, but i measured a used cometic HG as .032. so the pistons can be "in the hole" .008 and have that cr

another way to look at it is if the pistons have .040 for quench height you will get that cr with a stock stroke. thats a pretty standard number on a build.

Ryan are these standard CP pistons or custom pistons. CP makes 12.5:1 2mm over pistons and 13.5:1 for drop in stock displacement only.

They must be custom pistons as CP does not offer 86 off the shelf.
