Small Block Head Flow Chart

Buddy who i have mentioned before has a trickflow stroker.
Pretty cookie cutter bracket deal.
3100 ish pound A body, single plane, good flat tappet cam, yada, yada.
Had it out in pretty lousy air and went 10.50’s at 125 ish… very little tuning, doesn't get the car out much.
Fast forward to last week, took the trick flow heads off, swapped on a set of airwolf heads most of you are probably familiar with( btw, they are more like 210 than 225)zero other changes
Anyhow, car ran 128 with the airwolfs at similar ET to the trick flows..couldn't get the car to 60 foot decently.
Both outings were in similar 3500 ish foot air.
3 mph is a bunch…….thought it was a good comparison.. wish that Dr J cat hadn't flaked out on everybody. His heads make good power
