Have two Gen IV 454 ci 350 hp. Just replaced my port engine with new long block but was missing a box of parts needed to complete. Have acquired parts but before going any further need to know if engine requires a valley pan before intake manifold is installed? I will appreciate anyone’s response. Thank you. Vic
