Gapless top ring is a good deal..


The second I would not use as there is not place for the gases to go if its a sealed, Once you get pressure between the first and second ring to top is lifted by the pressure between the 2 rings.

Thats why most pistons have a groove between the first and second groove, Its called pressure seal groove or an accumulator goove. to give a place for pressure to build up so it will not affect the seal of the top ring.
