Different Degree Heads?
What angle is being measured for the various heads and what makes certain designs better.
There was an engine builder with a SBC that was all about some serious business. He told me that he is using 18* heads that were cut to 16*.
So please help me understand heads.
In addition to the angle, it seems that larger volume intake ports are better - larger valves of course, how about the volume of the chamber.
A thread about rod length in the tech section got me to thinking about some other aspects of engines that I have not yet grasped.
Thanks,
