Thanks for the input guys.

My 8 stack efi setup does not have a manifold per se. It has 8 individual intake runners (manifolds) and a valley cover over the lifter valley.

Each of the 8 intake runners have a “vacuum port” and I have “daisy chained” the 4 on each side joining in the middle.

I have fabricated a vacuum reservoir in the center of the valley cover which also acts as the pedestal for the throttle cable actuators for each bank of throttle bodies. (see pics)

The daisy 8 chained intake runner vacuum lines go into this vacuum reservoir, and I have attached the distributor vacuum (if needed) and will attach the PCV line (which I asked about earlier in this post) to the vacuum reservoir also.

Also attached to the vacuum reservoir is the IAC valve (Idle Air Control valve (see pics).

So I think I have the questioned answered.

Thanks guys.

Cheers
Greg
