This is an old chart. I was wondering if it was still accurate, for people running ported Eatons.
Reason I ask is I thought you had to close the gap on the plugs a little when you port the eaton.

I run IT-20s gapped at 0.032" and generally see 14psi on my Apten ported eaton. Saw as high as 17psi (once) and as low as 12 hot lapping.
