Frank, have you heard of people "gapping the rings" for such high HP setups? I believe my engine builder just used OEM 930 rings, but I've heard that for such big HP applications, these rings need to be gapped appropriately to accommodate ring expansion in big power motors?
I guess this only relates to track cars tho, right?
