Rebuilt Edelbrock, yea or nay

I got a Holley 4010 750 DP (4100 copy) needs a power valve and 1 pump. Their downfall was the stupid spiderweb cast base those carbs have, guaranteed leak on an intake unless you put a full size plate/spacer under them, gasket would not seal it alone. Nice carb though, all aluminum, annular boosters, all holley jets, valves and pumps work on them and the bowls are integral with the body, no leaks.
