440 crankshaft rods orientation question

I recently purchased a re-built 440 short block whom someone had speedpro flat top pistons hung on LY rods. The crankshaft, pistons and rods were obviously balanced.
Unfortunately, #2 main bearing went out on the crankshaft. (this is how I bought the block)
I am getting ready to install an replacement (standard steel) crankshaft in this block and noticed that the piston order is NOT as factory (ie. # 1 rod in #1 block hole.)
Rather, they are all over the place. #1 in #7 hole, #3 in #4 hole and so on.
I'd like to put the piston assemblies back as they were when I disassembled the block as the rings are already broke into the bores they were removed.
Can I safely do this? Why weren't they in the correct bores ?
Otherwise, I'll have to re-ring to put pistons and rods in the order they were assembled from the factory.
Not a super big deal, but would like to hear what you guys think. Thanks in advance
