sbp wheel suggestions for 64 Valiant

A while back I bought a 64 Valiant Signet. 273/904. I bought it as a running/driving project with the intentions of eventually going to a 360/tf. It currently has 13" wheels and I want to go to aftermarket wheels for the front.(I'm currently looking for an 8 3/4 bbp rear) The only sbp wheels that I can find (That I like) are Cragar 14x6 from Summit with 3 1/2" back spacing. Would this wheel be a good choice? I was hoping to find a wheel a little narrower. 4 1/2- 5" wide. Any suggestions? Also need suggestions on backspacing. I may use fenderwell headers so I'm not sure about the desired backspacing? Kind of an A body rookie here and I do appreciate the advice. Thanks, Litz
