I picked the engine up tonight and talked to them. They said the piston is right at .020 down and said the compression is a good 11.5

Any idea what it would be with the .026 gasket? The quench still isn't going to optimum but its better than the .041 gasket

The compression I am running is 11:1. LT4 compression is a bit higher due to revised piston valve reliefs.
