so what will cause more of a bottleneck first, the stock cams or the intake manifold. i'll be running a gt35r kit on stock heads and cams with a built bottom end. i wanted to know if i will benefit from getting the cosi manifold while using the stock cams with maybe reworked heads. would it be worth it?
