Best intake/carb for 360

Thanks for advise - Assumed valve covers would fit but was not sure if the extra holes were for something off that particular manifold and was not sure of how to seal off unused holes so no oil leakage and get a good look. The manifold seems to be a Edelbrock performer?? from comparing to pictures from summitt. Am new to mopar engines so am not familar to various setups.Anything (problems)I should look out for if buying manifold- fellow selling lives a fair distance away and is not very fast with pictures and info on this item. His price of $150 seems fair.
