to say Shapping and porting is simple, is no diff than saying rebuilding a engine is simple. its just not true. IT is a science i did not have the time or space to do a flow bench properly so i found an engine builder that was willing to work with me as i made changes to my heads. I would grind and he would flow. it showed me were i made mistakes and gains.
David Vizard is the god of head porting he wrote the book! or books on it. all our engines are the same internally let no one tell you differnt. http://www.popularhotrodding.com/tech/0610...r_head_porting/ http://www.popularhotrodding.com/enginemas...cylinder_heads/ |
