Yep, Corey's idit had rings that were wore very hard, especially in the center 4 bores. The outter 4 bores could have been rerung, but the inner 4 were pretty worn. I believe it was .006in over the max allowed and they were egg shaped. But I got it back from the machine shop after a .020 overbore, line boring, and balancing so the red trucks heart will live to see another day! Hopefully soon, haha! I'm anxious to see your dt swap when its done!
