I found a cast iron intake manifold for pre-vortec engine with vortec heads!! I have been looking for one my question is becuase its not a hi rise manifold will I be losing the hp that my magnum had! the heads will add 35 or so hp but if I have to change manifolds for one that isn't hi rise am I goign to lose that extra hp!!! so then my whole head and manifold change will only be worth 20 hp than its not worth it
