KB Dome Pistons in 383. Do you like them?

I’ve used them, a buddy has built a couple motors with them. Seeem to hold up well... be sure to follow the instructions about the ring gap.

I think a got about 11 to 1 with some 70cc heads
I'm hoping for a little over 10:1 that with a zero deck. Thank you for the tip on ring gap. Gonna run a tunnel ram. About 7k will be seen regularly so i went with the hyper to save a little weight in the RA. Custom grind on a .904 not a chevy blank. I'm hoping for a pretty stout 383. Thank you both for the replies.
