Racing flow benches

PRH said

The main point I was making, was as PBR often says........
You need the “before” numbers........ from the same bench..... to really know how good the “after” numbers are.

To say a head flows “x”, without the proper context...... is just a number.
And....... it’s best to look at the whole curve..... not just the big number.

if you read any of my posts on porting my first target and I’ve repeated it 100 times is over [email protected] and build from there. On my moved pushrod heads I posted I sacrificed my high number (332) because I wasn’t happy with my mid lift numbers so I reshaped the short turn to make a big improvement there because my cam was only .650 lift. The only time I ever charged for flowing heads was when I flowed two Hemi heads with different part numbers that a customer was afraid to run if they were to far off ( they weren’t). I learned something almost every time I flowed and tested a head so before and after numbers were always free of charge. As far as seeing differences at different lifts calibration plates are available from .100 up to verify this. My three plates cost less than 100.00
