I am curious to see what peoples on track results are when they start buying these heads. TF makes good stuff. Little hard to believe these dyno numbers with only a 295cc intake port size. But time will tell!
The exhaust port on a trick flow takes a quick turn compared to other bb heads. They get the exhaust out very efficiently. I was questioning it until we put them on a flow bench.Seems like a small exhaust valve? Isn’t the common upgrade for oem heads and some aftermarket stuff to 1.81? Does that not matter if they used the real estate to improve the port?
