Buy an M37 Manifold Assembly from VPW...

...and this is what you get:







It's so pretty I can barely stand it.

Might have spoken too soon...

I noticed that the intake manifold flanges and the exhaust manifold flanges are not flush with each other.

As you can see in the picture below, the intake flange hits the straight edge before the exhaust does. I feel like when some torque is applied it'll put undue stress on the flange...and we all know how much bending stress cast iron takes.

Is this the way it's supposed to be?

Whoops! You don't mount it like that. Either loosen the manifolds from each other, as the procedure in the manual states, or have the manifolds ground to the same plane. You do have a manual, don't you? Do it right, and have fun.

I see what you're talking about, here's what the manual says:


1,. Assemble intake Manifold to Exhaust 3lanifolcl. Lay straight-
edge (41-S-5858) lengthwise over the gasket surfaces of port flanges
of the manifold assembly to check for uniform height of the flanges. If
a O.OlO-inch feeler gage will pass between the straightedge and any of
the manifold flanges, Ioosen the cap screws which hold the manifolds to-
gether and shift the manifolds, if possible, to overcome the uneven con- dition of the flanges. If necessary, resurface the flanges just enough to
make them even.


It looks to me like it's a fair amount off. Also, it runs downhill. What I mean is that on one end of the manifold the flanges are farther off from each other than on the other end. This might be an adventure.

Edit: Alright, I did what the manual said and put it up against a straight edge. I loosened the bolts that connect the two manifolds and tried to make them even. No good. A little frustrating, but I think it's an easy fix. Still, it's the prettiest set of manifolds I think I've ever seen.

Update

I called VPW today. I told them the problem. They were very apologetic and said that someone in their machine shop must have missed a step.

They're having it shipped back to be reground and fixed free of charge.

I wish every company operated like VPW.
