Ring gap for nitrous?
As far as more or less gap than required for stock? This is for no more than a 150 shot on a stock bore 305, all I did was had the cylinder honed. As far as strength is a Molly top ring good?

More gap. Must compensate for heat.
Moly faced rings are good.
Forged pistons are better.
Forged pistons require even more ring gap.

What AJ said. More gap. If there is no published info on correct ring gap for mild nitrous use from the piston manufacturer I'd say that opening them up by .006" from whatever the N/A gap spec is will get you in the realm of sanity.
No, you won't have tons of blow-by by doing this. I thought I would, but experience has shown it don't to be the case.
Ring gap specs should always be taken from the PISTON manufacturer, not the ring manufacturer.
