Well I don't remember them doing any Cleveland stuff but those guys over at Valley Head Service were epoxying up B2 intake ports way back when the B2 was new to T/A., so other then casting up B2 Heads with intake ports to match 302W's intake ports, I would think that my small port manifold was made with thoughts of cans and cans of Devcon Plastic Aluminum getting put to use? At least experimentlly to try on the flow bench?
I will point out that my intake did come from So Cal. Maybe someone just grabbed it out of the scrap pile? It only cost me $100.
