Trick Flow small block heads

Me personally, not at all.. While I'm convinced there a superior product in most every way, I'm not convinced of the bang for the buck..
I'm hoping @69lead comes to the track one day and I can pull out a can of whoop-*** with my Speedmaster heads LOL.. and if he even thinks of getting close I'll just push the button and let him see my tail lights LOL...
From where I sit, swapping to those heads is a wash for the absolute grand total I have in my W5’s. By there numbers, they should perform very well.

As long as your power to weight is in your favor, you’ll do fine. Doing more with less has been my life long bain.
