Bore prep for short skirt pistons

I am building a 393 clevo, and I am wondering if the bore needs any extra prep when using these short skirt pistons. I was under the impression that a small chamfer on the bottom of the bore was benificial.

I have just picked up my block from the machine shop for dummy assembly and noticed that they havent done this chamfer. Is it needed or not?

I also notice a slight chamfer on the top of the bores edge. Is this normal? I am hoping they havent chamfered the wrong end of the bore

I don't know about the bottom of the bore, but any block i have had machined does has the chamfer at the top.

PUT THE CHAMPHER IN! I purchased an engine a few years back and on dis-assembly.....all the skirts of each piston looked terrible.....got to looking at the bottom of the cylinder and noticed that they were not champhered......I was able to salvage the pistons........Any sharp edges on the block around moving parts should be done.......
