The other issue is that the pushrods are designed for the aluminum cylinders that came in the SC. They require a different valve adjustment than the old style pushrods and old style cast iron pistons.
First I would have the cylinders carefully measured to see if there is any chance you can get more life out of them with new pistons. If your Biral cylinders are worn out (assuming it still has them) my preference would be either the $700 cast iron cylinders from Pelican or the $1300 cast iron set from Stoddard. You still can use the alloy pushrods that go with the aluminum cylinders if you adjust the valves to .005" (intake) and .007" (exhaust).
I see Pelican sells "Stoddard" branded P&Cs but I can't find the same P&Cs in Stoddard's catalog. Stoddard does sell cast iron P&Cs but only for A or B engines and does not list them for SC/912. I assume the pistons are too long to go with the counterbalanced crank, but who knows. I would call Pelican and call Stoddard and get more information about the $700 Pelican P&Cs and the $1300 Stoddard P&Cs. Please report back if you do so.

Thank you for the info. Are the Biral cylinders aluminum with a cast iron liner? and I assume after 55+ years this motor may have been apart a few times and who knows what surprises we may find?
