If you where building a 261" stage motor with a self imposed shift point of around 7200 to 7500, would you go with a set of stage heads with the big runners or would you go with a set of smaller runner heads? I have an oportunity to pick up a top notch set of "Velocity Ported" stage 2 heads. The intake port openings in the heads I have now are 1.35" wide by 2.35" tall w/ 2.100/1.600 valves. These smaller heads are 1" wide by 1.900 tall with the same 2.100/1.600 combo. That works out to be a port opening only 60% as big as the bigger heads. With this motor only being 261", my relatively small cam, and the fact that I want to make most of my power close to 7000 rpm's I'm leaning seriously towards picking up these smaller heads.
