Just out of curiousity can you tell me where you've gotten all those intake manifolds to fit the W2 heads or are they an econo look alike with the same bolt patterns?

You can redrill the intakes to fit, not a problem. Port matching could be though. Also, years back Batten offered square portr W-2's I beileve.

Indy has square port W-2's right now.
