.031" Dykes or .043" Rings ?

My LT-1 had 1/16" top ring grooves and I used std. top rings with cutback seconds and very low tension oils......I have used the .031" dykes with spacers in a 5/64" groove if I remember right in my 350/255 back in the '90's......Do the .043" rings go in a 1/16" groove with spacers.....and the rings are where the gas port grooves are cut ? .......the spacer would be pretty thin and I have no experience or knowledge of the gas ported ring setup. Just curious about this and I might need the knowledge for a future Stocker engine project for someone else........
