I have a guy here locally selling a set of freshly rebuilt GT40 heads. My question is how much of an improvement are those over the stock heads on my '92? He is asking $300obo are they worth the money for the power gain? Is it that much over stock ones or am I better off spending the money on some Trick Flow 170's or AFR's? I know heads are a big increase in power but if the GT40 style are a minimal gain I don't think it's worth wasting the money? Anyone with some insight?

Follow the Links and it will tell you all you ever wanted to know about the GT-40 heads.

Bottom line is that gt40's max out at about 300 HP with all supporting mods. Expect more like 275hp.....

For 300 bucks they're not bad heads at all, but they don't put out nearly as much power as AFRs or TF heads, but those are 12 - 1400 dollar heads. I built a 302 a while back with some GT40 heads and i put down 280 to the wheels. If you're happy with that kind of power, go for it, if you want to put down more power later on, save your cash for some $1300 heads. I love my AFR heads (see my sig)
