Which piston rings to get?

[Pablo]

I have the TRW forged pistons .030 over.

I'd like some standard tension file fit moly rings.

When ordering file fit rings for .030 over bore, are they labeled as .035 rings?

I'm looking at these two rings
Speed-Pro Piston Rings for Buick at Flatlander Racing

speed pro r10499 only has .030 listed

r10437 lists .035

which is the correct ring set for what I want to do? Please help asap, I'm trying to get this ordered today

 

[Pablo]

also, can I just get the sealed power moly rings and use those? What I am wondering is if the gap they come with is smaller than I would use anyway and whether or not I can then file those to work. Those rings are significantly cheaper.
Is there any major difference in performance between these rings?

yes

You will need to order 3.835 ring set to be able to file to your desired end gag. I like .017 top--.020 second and .016-028 oil ring @ that bore size. Best of luck.
