Default 5.3 Piston swap

I have my 5.3 at the machine shop having some work done and they are having trouble getting my paistons off the rods without having them crack. I wouldn't worry about it but they are yaking a set of 4.8 pistons (Flat top) off the stock rods to put on my 5.3 rods and they fear this will occurr on them also. Is there a trick to this procedure?

Have them bore it and install 5.7 hyperutectic pistons in.They run around $25 each


Its risky trying to get off used pistons to be re-used,going back in is easy though,they heat the pin.

They don't sound like a very good machine shop. I did my own last weekend in my own garage. You just heat the small end of the rod so the pin will go in or out. I had no problem whatsoever.
