You weren’t really expecting them to after looking them over and flowing them though.
And..... the TF’s are less $$$.
Here the test....... two sets of heads.
The TF’s right ootb....... do nothing but bolt them on.
The other set, some RPMs that you buy new, and upgrade only as much as you can, and have them not cost anymore(customer price) than what the TF’s cost.
Dyno both on the same 550hp plus capable short block/induction/valvetrain.
See how they stack up in the bang for the buck category.
