Inliners International Forums General Discussion Engines pontiac 4 barrel intake/exhaust on a 250?????

I was looking at that on ebay and wondering why I'd never seen such a nice clean manifold before! I was so sure it was a 250 L6 intake. I thought the OHC 250 was basically a 250 L6 with a OHC head? Or I guess they reworked the intakes with the new head?
