my first engine rebuild (318) advises

i have been reading more and i have some questions about piston rods and wrist pins.

So stock 1972 318 engine should have floating wrist pins, not pressed?
so can i use stock wrist pins with kb167 pistons or do i need new pins?

Piston rods are other thing that i want to ask.
i really dont know that kind of abuse rods have taken in last 40+ years, or have rods been removed before.
Thats why i am thinking, do need new rods, if so are these correct?

it will be brobably cheaper here to just buy new rods than recondition old ones.
