Question about ring gap as it relates to "hotter cylinders"
I'm working on file fitting my rings and I am curious if any of the LT1 cylinders typically run "hotter" than others. Reason I ask is I am gapping my top compression ring at .022" and the second ring at .024" and on a couple of my second rings I went a touch too far at .025". While .001 is not really a lot to be concerned about, I'd prefer to put these into the cylinders that typically run hotter since they will expand a bit more.
My guess would be cylinders 3, 4, 5, and 6 would run hotter than the rest since they are the 4 in the middle of the engine with more heat surrounding them. Thoughts?

I have no idea on the LT stuff....but on the LS stuff, #5 & #7 were always the hot ones. I didnt gap them any differently, but I did put the best flowing injectors on those two. And those were the two I always melted. LOL
.022"-.025" will be fine. I did find that I had better luck with the Total Seal AP steel rings vs. the Wiseco GFX rings. They seemed to handle the heat better. I pulled a set of GFX rings out after 3k miles when I got into a little detonation, and the rings were closed up on 4 cylinders...(lost tension).
Good luck on the rebuild
