Is that a Super Flow or what brand?
Dyno numbers are just that, a useful number(up or down) to compare changes made on THAT DYNO that DAY work
I'm glad to see your test results posted, I haven't use a set of the Trick Flow heads yet, either size shruggy
I did see 50 HP difference from a set of Indy SR M.W. compared to a set of CNC ported 440-1 with the same intake. same carb with same jetting, same compression ratio on the same short block with no other changes except the heads work From 727 HP up to 775 HP up
