I have a 383 that the heads have not been milled on. I tried to install a new torker 383 intake manifold with no luck. At first I had a gasket between valley pan and block, gasket between valley pan and intake. I could not get the intake bolted on! I currently have the intake bolted on the engine, but I had to remove the gasket from between intake and valley pan. So currently I have A gasket between valley pan and block, but no gasket between intake and valley pan. Will it leak with this configuration? I know, I’m a idiot! Lol! I have read of people using valley pan with no gaskets at all, that’s the only reason I’m considering it. Thanks for reading this mess!
