AFR's all the way. With the 351 I would go with the 185's. The AFR is a great street head. In the case of the 165's, the intake runner is small which keeps velocity up, but they flow as well or better than just about every other head out, even ones with 2.02" intake valves and larger intake runners. This way you get great flow and great velocity- just what a street motor needs. The 185's can be a bit much for a 302, but with the added displacement of the 351, the 185's would be a better choice. Someone correct me if I'm wrong but I believe that even the 165cc AFR outflows the edelbrock performer RPM. I must say though that the edelbrock heads are great pieces with outstanding quality.
