Re: 1964 GMC 3/4 ton build :D
Maybe it will be a good thing to go with headers, might help keep the engine cooler under loads, pulling rice burners or whatever you need to pull. I'm installing the headers on mine, only because they are what I have. I got the right side on, and to tell you the truth, they do look cooler. Those manifolds look like headers. Do they turn a 90 degree at the bottem?
