Maybe I am but not real sure. I posted that chart at the beginning of the thread as well. Just needed some help understanding it. And I’m not sure why your saying .0015-.0020 when the block is .030 over and I’m setting gaps for nitrous. I’ve spoken with my engine builder throughout the machine work (And the direction I wanted to go)which is now done and complete. Now I have the block and am ‘absorbing’ new info with the new challenge ahead by reading and asking opinions of members here willing to help. These guys have done builds like mine before where I haven’t so input is welcomed. Thank you for your input
