So I am considering buying these heads from a guy that says they have been drilled for a 351w, now How do I install these on a 302 since the holes are opened up more?School me on this one please, bolt size? washers? what do I need to do?

Yeah, you can either do the washers or ARP also sells a 1/2" shouldered bolt with 7/16" threads. Either way works just as well. The washers are probably cheaper.
