Reply to "Intake question"

Ford used the A331 part number for two different manifolds. The first was the "modified torker" manifold, which is the one you acquired at Pomona, the second was the Jack Roush high rise version, such as in 4V's picture.

The manifold you purchased has runners that were resized for the first aluminum SVO race head, known as the A3 head. Prior to the introduction of the alloy A3 heads, race teams were eliminating the "funnel" at the entrance of the iron 4V intake port by filling-in the floor and the left hand wall of the port entrance up until the push rod bulge, the roof of the intake port was raised as much as the casting allowed, about 1/8 inch. The ports of the A3 head and the runners of that intake manifold emulate what guys were doing to the iron heads.

Technically you could fill-in the entrance of your iron heads as I described, and thus make the heads compatible with the intake manifold. But it would be much simpler to purchase the Edelbrock Torker designed for the 4V heads to begin with, therefore you wouldn't have to modify the iron heads.

That A331 intake manifold was the only manifold with runners sized for the A3 heads, it is quite rare, if it isn't buggered-up its worth a lot of money to the right persons. I'm not sure how much anymore, I'd guess in the range of $600 to $1000. So I hope you've made a nice profit.
