I remember reading somewhere on here but cannot find it that you are allowed to use as many cards as you want(legally) between rest periods upto a mximum of 144 hours(6x24 hour period), am I correct in remembering this?

Yes.

In the UK you can legally do as many shifts as you can fit into the six periods of 24 hours (144 hours) between weekly rest periods.
