Head porting flow numbers
This is a Stage 1 head with stock valves.
INTAKE
.100 75.48cfm
.200 133.20cfm
.300 189.20cfm
.400 206.80cfm
EXHAUST
.100 63.64 cfm
.200 113.96cfm
.300 171.60cfm
.400 184.80cfm
Flowed at 28" air temp 96degrees with 60% humidity.
there are still more that can be had without cutting the plenum off and still keep things reliable. I have another head i will be doing over the next little bit so I will try a few more things.
