Ring Gap with 150 shot Heres my issue, I asked the machine shop to file fit my rings to the end gap of .020 and .022 according to Weiscos gap chart which is "street-moderate turbo/nitrous"

Well instead they must of had some miscommunication and gapped it for the "nitrous race only" which is a gap of .028 and .030. I find this rather big for a mostly street driven car that will be spraying no more than a 200 shot. Any advice would be awesome.

That gap will be fine. I am running .028 and .030 with wiseco pistons, the larger gap is the second ring to prevent flutter. It has worked well all season running a 150 shot. I am currently upgrading the fuel system and will spray 200 until November then this winter I am boosting the car with a billet 80mm.

I'm excited to see your future set up sounds nasty
My car is a street car and I have no blow by and use no oil. A solid PCV system is critical with these LS engines though. You will have PCV issues long before ring gap issues as long as the cylinder wall hone and ring install is correct. What does your machinist say about it?
