Doing a ring job on a what appears to be an original engine from a '65 (was blowing smoke badly as I wrote about in an earlier post).

Pistons are marked D and measure 3.309" (mas or menos)

Not replacing pistons in any case. Hone, new rings, head & pan gasket, and back in the car.

Question is what ring set (size designation) am I looking for.

Deves? and plain, not chrome.

Best source for rings, inexpensive and in stock?

thanks

trying to order today

Didn't see anything indicating source of high oil consumption from pistons and rings.

Cylinders 2 & 3 had more deposits on the pistons and was wondering if anyone had experience with oil loss into center cylinders due to oil loss from oil gallery supplying rocker stand. Seems like water gallery leak would show up first, but just checking to see if this is a possible source.
