139 CFM at 28" Water at .500" Lift on intake.
70 CFM at 28" Water at .500" Lift on Ex.
Our Drag Race/Boniville head is at
207 on Intake
160 on Ex.
Raise the roof, and braze up the area around the head bolts so you can raise even farther than the original casting on the ex.
On the intake, We took a boring bar and enlarged the 4 Openings about .375" then soldered up where it went into the water, and worked the bowels from there.
