How to Install New Pistons on Old Connecting Rods?

I was practicing the soon to be lost art of reading, with the book, "How to Rebuild a Mopar Small Block". The author said that the connecting rods would need to be heated and then a special press used to press the pin out from the rod and piston. Is that true?

Prior to reading, I was planning to install new pistons at home, without the use of heat and a hydraulic press. Please advise.
Let’s start with which engine you are working with. LA or Magnum and size? They are not all the same. From my poor memory the 340 and 273 use floating pins so no heat needed. 360 are pressed and need heat. 318 I’m not sure but I want to say floating too.
