Ross is all I use in my Pontiac motors. However I pay a lot more than $675 I buy them with their low friction Teflon impregnated hard anodizing that adds about $200 I get mine through SD Performance. I highly recommend the coating as it’s even in the ring lands so the lands never wear. As for the quality I didn’t know they are being made in Mexico now but by the measurement data they provide with the pistons I see no issues. For rings talk to Keith at Total Seal for about $400 he will set you up with a great low drag set with gas ported spacers. As for Rods cheap aftermarket like Eagle work just fine. These Pontiac stocker motors don’t spin that high that you would need something like a Manley. As for this compared to TRW pistons with stock rods, there is a big weight advantage with the approved aftermarket rods and pistons you can get down close to NHRA speck weight. If I recall correctly the last 400 I did with factory rods and TRW pistons was about 120 grams over minimum, that’s quite a bit in my opinion.
