If I stay with the stock rams horns, do I need this valve thing bolted between the right manifold and tubing? What is it good for? Am I right understanding it only to be a less important cold start "helper"?

I think I will go with the edelbrock since I can get one cheap. Will it work with the stock manifold and adapter?

Thanks for you help, important to me as always...
