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.

————stock (my bench). Pinch work
.100———-67—————74
.200———132————-133
.300———195————-199
.400———245————-248
.500———280————-283
.600———298————-298
.700———300————-307
.800———300————-309
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
