64 Valiant V 200 aftermarket tire / wheel sizes.

64 Valiant V 200 on this end. Want to run aftermarket wheels and tires. Looking for staggered look having the back of the car raised. What size combo will fit without rubbing? Going to also see if anyone on the site is selling what I'm looking for?? I do have a full set of small bolt indy slots here i can use that are 14X6 and 14X7. Just need to know specifics as tires are 900 bucks and want the right size, thanks in advance.
