My second gap is larger than the first. My actual piston card called for .016. I felt that was too close and for my boosted app went with .020 top, .022 second. I felt this was heck of big for a low boost engine, but better slightly bigger than too small.
4.065 bore x HP racing of .0053 = .0215, so I'm slightly tight on the top and slightly loose on the bottom. To be honest I think they are slightly loose for my application.
I'm boost / octane limited on 11.5 CR and this is a street car so single through the gear WOT runs.

Thanks Oldman for this input
Do you have the data for the typical stock LT4 ring gaps?
