What would the ring gap be for the 2 compression rings on a 454 bored .030 over?

CN,
There are several variables that need to be identified to answer the question. First of all, which pistons and what does the piston manufacturer recommend ? Second what is the intended use of the engine ? Any power adders ( blower, Nitrous etc) Third, which rings ?

I generally follow the piston manufacturers recommendations.
