I have a nice W2 intake manifold for small block Mopar engines using W2 cylinder heads. All threads are good. No pitting. Nor porting or modifications to the intake ports or plenum. Two of the bosses were ground down a little to make room on the right side for a dual feed Holley fuel line. Great used manifold.
Price is $300 plus shipping.
I also have other single plane W2 intake manifolds, iron bushed rocker arms, W2 offset drilled shafts and other W2 parts. Let me know your needs.
