Steer away from the big ports if your intentions are towing. It will kill low RPM air speed where you need torque the most.
Okay after reading your post I did more research, I appreciate all feed back as I am learning as I go on somethings. Towing isn't the goal but more low in torque. So since the head I have is for domes pistons. I could track down the 270 head. For the flat top pistons. Do you think that would be a better application for low end torque and daily driving?
Thanks
