Re: Are the heads and manifold on an EL XR8 restrictive?
The intake is more restrictive than the heads, but it is close. Also fully ported E7's flow about as much as the stock GT40P's, that's why I went for the GT40P's in the first place. The GT40P's can also be further ported, I am doing mine this week. As for intakes, anything from ford with the GT40 base (Explorer, cobra or GT40) would be a good upgrade or just go for aftermarket edelbrock or trickflow ones.
