360 heads on a 318. good idea?

There are a number of intake manifolds that are able to accommodate your suggested configuration. I am putting a set of 340 heads on my 318 and I got an RPM Air Gap (7576) from a FABO member that he was not using. What a huge difference in the size of the ports compared to the 318 intake!! Edelbrock specifically identifies the combination that you are talking about using. My 650cfm Thunder AVS carb arrived in the mail today and that will make a nice addition...
