I just bought a 302 out of an 80's truck and I plan on more than just a mild build but also wanna save money where I can. I learned about gt40 and gt40p heads and I fell in love and wanna do that instead of the much more expensive route of aluminum heads. But I'm new to the 302 world so I don't wanna mess up. I looked up gt40 heads for sale and summit popped up with the vege and they are a super good price I just wanna know are those actually gt40's or just as good as gt40's I see that they have the three stripes on the side like gt40's do
