Hi Chiefkey, More info below from researching PART NUMBER L2251AF. There is a set on Ebay for standard bore (see link below).

Full floating. Retaining lock clips are missing. Each piston with the pin inserted weighs exactly 1 LB 13.2 ounces. Let me know if if you have more questions.

1.715 COMPRESSION DISTANCE

.240 DOME

1/16 1/16 1/8 RINGS LANDS

8 PISTONS AND 8 PINS

LOCKS FOR THE PINS ARE MISSING

Those are great old school pistons. The dome can be milled down if desired fwiw.
