Small block TrickFlow heads part 1

Intake flow numbers. Now remember I worked the pushrod part of the pinch and never touched the common wall, roof, or floor. (I will be) speed at the pinch was slower but as I knew it would be still high. I will try to give better details on that tomorrow. Ohhh I did remove that slight ridge I talked about earlier in this post. Cnc always leaves a slight lip.

at .850 lift this port finally went turbulent BUT and this is odd when I backed it off to .800 lift again it immediately calmed down. I find you usually have to drop the depression to calm it. As you can see these were small gains but now we go for it. I forgot to add the exhaust port pictures to see the small mods on the exit so I will add them here this will be dressed up more before it’s done View attachment 1715804343
