Not saying you're wrong by any means but a lot of high-end Racers have preferred the iron heads because the combustion chamber holds all the heat in a lot better and heat is what makes power all of the Chevy stuff I built for my customers when it comes to a street strip motor I put in almost an extra point of compression when using aluminum cuz of the heat dissipation of the aluminumBut air speed is only one factor. I'll choose an alum head over a iron

More low end torque and better throttle response,so nice on a street engine. Add E85 and you have even more torque.when it comes to a street strip motor I put in almost an extra point of compression when using aluminum cuz of the heat dissipation of the aluminum
I chose TA because after a year and a half of waiting for some from Champion I lost patience. I do like TA's more robust casting as evidenced by its weight. They have a very thick deck.Hey guys now we got rid of the technical stuff which head did you choose and why Champion or TA.
