Hello Sean1972.
You might find this Briggs & Stratton pdf file useful for your search:
http://www.odref.com/briggsandstratton/model-25/251400-ms6370-0582.pdf
It lists part numbers common to engines 251400-251499. Piston sets come in standard size, as well as oversize. The illustration you want is on page 2, and the part numbers are listed on page 7.
You may be able to find aftermarket kits for your engine in addition to the original equipment Briggs & Stratton parts. You will use the part numbers listed in the pdf as a starting point for other sites to cross reference.
Double check that the model and type numbers you are using are correct. I can see how these are not helping, since using all the numbers you supplied fails to designate useful links.
By the way, the starting point I used for this search was:

I hope this helps,
