Speed Pro Piston Rings R9343-need advice

Hello. I am building a turbo 351W. MP-T70 Turbo. HP goals 550-600rwhp. I am using TRW/SpeedPro L2446F-30 low compression forged pistons. Heads are AFR 205's with 69cc chambers. My question is this. Will I be ok with the rings in the title? They have a ductile iron top ring, cast iron second ring, and stainless steel std. tension oil control ring. They are file fit and the ring size is .035. So will these be a good match to my combo? Also, how do I find out how much to file from the rings? Thanks a lot guys/gals.

Place the rings in bore about 2 inches down then measure ring gap with feeler guage.. Boosted engines require extra ring gap.
Mine are gapped at .028 top and .030 second ring...
You can run yours tighter at your power level....
Rings are ok also at your power level....
