I recently purchased a 5 carb McGurk intake manifold that I plan on installing on my recently rebuilt GMC 302. Since the motor is stock, I plan on only using the two outside carbs, and center carbs, blocking off the other two. SInce the manifold does not have a heat riser, do you think I will need to add one? If so, how should I modify it so that it still looks right??

Anyone done this before, I would like to see photo's.

THanks
