Enough is enough: None of you guys are allowed to continue the "Edelbrock vs. the Iron Heads of the World" argument until someone actually puts up some dyno numbers or track times. We don't race flowbenches.
Seriously.
About the Indy heads:
Hughes says " On the heads we checked the tallest spring installed height we could get was 1.627". Note: That was achieved using this tall retainer in which the stem barely clears the retainer, about .040". INDY tells us that the spring pockets (bases) can be cut up to .100" which would result in a 1.725" installed height. What this boils down to is that for most applications you will need to have the spring pockets cut."
So the max spring height you can get is 1.725"??? LAME.
They also say that they had to tap the hold down bolt holes because they weren't tapped very deep. Nowhere near as big a deal, but still.
