Mopar W2 heads intake runner volume

Simple question time. What is the intake runner volume of cast iron W2 heads?

I see Jegs and Summit still sell them, but they don't say much about them past the combustion chamber size, and that they require special rocker arms and headers...

There have been a couple of pretty good TECHNICAL posts on W2 heads over on Abodysonly lately.

You can get that info from the NHRA tech/racer page. They have poured volumes. Look under SS specs.

Not for W2 heads. Never came on a production engine.

2001 MP catalog shows 185cc.

Thanks!

I own a set of the econo heads and can't believe I wasn't able to find that info anywhere.
