Very old Wiseco. The XC is the ring style. Might want to measure them for taper. There should ne at least .002"

Thanks Jay, Can I still get rings for these pistons? Also I have a set of cams that came with these pistons do you have a idea as to what duration and lift they are the numbers on them are CWC EP_14 also has I-5 and c2 on the ends of them. Thanks bunch"s

Yes the XC rings are available. We stock them.

As for the cams, the CWC is the billet manufacturer, the EP14 is the billet part number.

The I 5 and C2 would be the markings that tell what cam grind it is, but I don't recognise them.

you should be able to get the lift and duration with a mic and a degree kit
