Also. I wanted some input on where the final compression ratio should land. As it stands now, it's at 9.47:1. But I think there's enough material in the combustion chamber to get down to 9.0:1. I feel like 9.47:1 is kinda high but I'm also not very familiar with anything but the 8.5:1 and 8.0:1 I've run.
