Good day,

I need to order a set of piston rings for my 440 0.30 over.
Somebody suggested to me the Total Seal rings but the Part# offered by 440 source for the 0.30 over engines (CR 6490-35) seems to be 0.35 over so i don,t know if it will be very much¿?

In the summit page there is another Part# available (CR 6490-30) wich i suppouse that will be 0.30.This one is not "File fit" like the other one

Does know somebody wich would go better?
Are the file fit rings better?

Thanks in advance for the help
