My guess is the HP was a lot lower then they expected and TF told them not to put it on tv.
That’s the problem with the huge hype of a non tested head. It the labeled the best SB head without any proof/dyno #’s or time slips to back it up.
I dont think it was a problem with the heads as much as the combo choice.
If TF wanted to use this as a hype for marketing they should have specially prepped the heads and chosen a more aggressive solid roller . 260ish @ .050 on a 108 with .600 lift and 11.1 compression.
