I'm with 428 on this, but, without high jacking this post, I do have a question.
In years past I've had issues with the base of the carb freezing up with just the simple addition of headers not backing up enough heat to keep the plenum warmed up. With after market heads and manifolds with no exhaust cross over do you guys have similar experiences and if so whats been your approach to keeping the carb from icing up. I understand the need to keep the fuel charge cold and dense but I'm thinking there might actually be some advantage to leaving the shield out in the absence of manifold heat. Your thoughts??
