I was watching engine masters and saw this test and saw this https://youtu.be/TvQHgt-tF7Y The two alu rockers were different ratios and produced diff results so how do you know what the correct ratio is for your A series. Just by the way there was also this https://youtu.be/8VjFZMKvEwY How does the rocker ratio and cam /cam lift etc work together? I see yellaterra also has diff ratio's
