S&S 107 to 113 question

[poppinsmoke]

Gentleman, I bought a S&S Evo Super Sidewinder bottom end with the 4.25 flywheel assembly, it was paired with 4 inch bore jugs for a 107CID engine.

My question is I know the S&S built 113 engines were a 4 inch bore with a 4.5-inch stroke, but can I run 4.125 jugs on my 4.25 stroke to get to the same 113cid?

The cases are S&S 31-0024 the same cases that S&S used with 4.125 bore and a 4.625 stroke for their evo super sidewinder 124 engines, so I am thinking jugs and pistons should be available?

Any thoughts?

Thank you in advance for your time and consideration.

S&S would be the best place for a definitive answer.
