Default Rings & Pistons

I'm a believer in Ross pistons and Speed Pro rings, and here is an eye opener for you--- You want to gap your second ring wider then your top ring. You ask why? Speed Pro has discovered through R&D that the gases that escape through the top ring gap to the second ring will lift the top ring off the ring land from the bottom if the gases can't escape through the second ring. Some pistons have gas holes drilled in them to alleviate this problem.
I would check with your ring & piston MFG.
