I'm very new to engine building and have been trying to pull as much info as I can from the machinist who's doing my engine work because he's been building race engines in his shop for 20 years. He told me when I gasket matched the exhaust ports not to remove material on the tops because it would slow them down. Rather, just remove material to shape the exhaust runners to match the direction my header pipes are initially pointing, maybe cupping the tops or side a little bit where it's necessary. This makes good sense to me. I'm trying to lead the gasses with the shape of the ports.
I thought of something that I thought would make the log flow a little bit better but i'm not sure if it would or if it's been done. It has to do with the 90 degree turn the a/f has to make to get to the #1&6 cylinders. What if there was something attached to the freeze plug inside the log to help radius that turn.
Also, something under the carb inlet(like a hump) that would be centered and radius that 90 degree turn the fuel has to make to the 4,5,6 and the 1,2,3 cylinders. I don't want to do this on my modified log head because I'm sporting a direct mount h/w 5200 and I think it would do more harm than good. But it would seem to help on a carb where the a/f is coming through the carb hole equally at all times.
Am I on the right track with my thinking? Again, has anyone tried this before and are there any appreciable flow gains to be had for the #1&6 cylinders on the intake side?
