GT40X vs AFR vs Twisted Wedge
So, do you think it would be worth the money (after selling off the GT40X heads) and my time to replace my GT40X heads with a pair of Trick Flow Twisted Wedge or AFR 165s?
I installed these GT40x heads back in Jan 09 and I've just never been convinced that they are the answer. I've been trying to gather data (mostly magazine tests - however accurate that may be) to support one way or the other whether it would be worth it to switch them (given my combination) for another set of heads.
Seems like a bit of a gamble since different motors will respond differently to different parts, but I'm curious what you might think.
Sorry in advance for the "which head is the best thread."
