I would try ERA as alot of there gt40 kits have the 180 degree headers and they are known for the quality of there kits.I have seen a couple of the kits with 351w motors in them.Im not sure if they have the 180's for a 302 but worse case just get a set before they are coated, cut and reweld them so they fit the narrower 302.302's and 351w's have the same exh. ports on the stock heads but are different on aftermarket heads from DART,TFS etc.Gt40 headers should fit but i would get the exact specs(Such as how long and high they are) first.Good luck!
