Handy vid mate I'm in the middle of my L20B stroker now. Only I thought the top ring is usually gapped wider than 2nd due to the extra heat it sees at combustion?
I am no expert by any means but everything I have seen shows tighter top ring clearances to minimize blow-by. Of course you don't want it too tight that it breaks the ring land. Follow your recommend specifications from the manufacturer.
