New big ends: end float

["Slack Alice" Simon]

Good evening, assembled gurus,

What, if any, is the recommended end float for big ends on a re-ground crank with re-metalled rods?

3 of the rods move back and forth a little, the fourth not at all, though not tight, since the engine turns by hand.

I have yet to remove the block and see if they have been "barrelled" - or whatever it is called.

Thanks

Simon
