Your new rings should have instructions with ring gaps depending on what application you are going to use them for.

^ he's correct, but you said the magic word "hyperujunktic", read the instructions that should have come with your pistons, and use the gap they specify. I always add extra gap on the top ring for those pistons to keep the top ring from closing up and lifting a ringland.

90 GT 393 5 spd, 467 rwhp 480 rwtq > Sold
92 coupe, R/S 308 5 spd > Sold all engine parts off, coyote power coming soon..
93 coupe, 2.3 5 spd > still plugging along...

As above I also add gap to the top ring for safety.
