W2 intake manifolds pics

The Holley Street Dominator and that water heated M1 are the same exact height. I have had them side by side with a level at center bubble.

Hmm. Not mine, but it's hard to see in the pictures if the M1 is an "air gap" design like the Holley STRIP Dominator, which I assure you is taller than the STREET Dominator. I have a water heated M1 which looks Strip Dominator-ish, but I haven't measured. Thanks!
