If you have real 302 heads they will have 2.02/1.60 valves and will bolt on and should work pretty well on the 383. You will possibly leave some HP on the table compared to after market heads but it shouldn't be a dog by any means.

As far as the budget goes, if the heads are ready to bolt on it it is definitely a viable option.....if they need everything (seat, guides, springs, valves, milled etc) then you are probably money ahead with aftermarket heads, especially for what those heads should bring to a restorer.
