Best piston for street/strip 340?

As several have said , The KBs are good if you gap the rings like they say. I had a set in a daily driver for six years , lots of miles . Now the same set are in my oldest son's 360 ,
been in there 2 years. The speed pro h116 is also a good piston .

Speed pro 116 is a360 piston not a 340
