This is an oops! moment. Didn't see the words "sonic check" anywhere in your posts. Before I bought pistons I'd check and make sure your block is going to hold up. Better to waste the block prep money than to waste block prep AND piston money! If you're spending $400 or more on run-of-the-mill pistons, throw another couple of hundred in the pot and you can get a semi custom piston that fits your needs. Diamond comes to mind. It usually doesn't cost a lot to make a simple change to a shelf stock piston. To look at a lot at once, try www.flatlanderracing.com or www.campbellenterprises.com.For example, I found that Probe and KB make 440 pistons in 0.060 over. Then I'd suggest buying from a board member who is a dealer. R.

Yep, been there. Got a .058 over block & almost all pistons are .055 over as you mentioned. Ended up putting the block under the bench. Speed pro has one as mentioned above but you're going to have to hone it out a little for clearance. Also they way a ton. Not any lighter than the originals. I bought 'em, weighed 'em & immediately sent them back. It was somewhere in the 1125-1150 gram range with pin, I believe.
Honestly, I would get a set custom made if you're set on using that block. That way you can get the skirt clearance you need without the weight of the junk Speed Pros. Some guys don't charge too much extra just the wait time.
Oh ya & even if there is a listing for a .060 piston chances are it's not on the shelf at the manufacturer. Called them all back in may-june. They rarely run that piston/size, once a year or some b.s.

I think most of those I posted can be bought in 0.060 over, plus the Probe pistons, KB ICON, and Ross. What heads and compression ratio are you looking at using?
Custom pistons can be bought, but check around on the cost because some can get over $1,000/set.
The list I used above was when researching low cost pistons for a mild street engine. I think the 440 source pistons are KB ICON brand, but for aftermarket rods with a 0.990" pin.

Oh they list 'em but don't usually stock them, manufacturer that is. I called Probe, JE, KB etc. when I was looking & they all said they only run them once in awhile. Also have to ask the actual skirt measurement with each manufacturer as they differ. Don't have my notes with me but just a warning on that as they all have different skirt numbers.
Get in touch wit ha Diamond WD and get a semi custom , it's only a small upcharge if you go with a shelf stock piston , tell them where you want the pin and what your bore size is and you are all set . I'm going to be doing a 4.365 bore piston in the near future, same boat as you the bores cleaned up at that size .
