what is the application? since you got wiseco pistons ill assume that you are going for big power. so gap the top ring at .019 and the 2nd ring at .017 (inches)

am looking at above 400hp so this is a good start to begin my investigation at.

If you're using 86.5mm pistons, I hope you're putting them into a 2.0 not a 2.2
