Spark knock

Start with what I got. 1980 360 bored 30 over,kbp 190. Comp cam 525 lift intake and exhaust. Stock bottom end and stock heads.stock trans and 7 1/4 rear end. My concern is I just replace my intake manifold from a offenhouser dual plane to an edlebrock air gap intake dual plane. The gaskets wernt sealing and sucking a lot of oil. And I hated te offenhouser. With offenhouser I had no spark knock no problems. With this new intake it's fine cruising and litely into gas. But when I hammer down on it. It spark knock like crazy and buddy if mine that was falling me says there white smoke. I run 93octane and a 650 speed demon vacuum secondary and run a stock ignition box. I just don't want to mess up my motor any ideas
