elderbrock performer 600-750,, or stock 625 afb ??

i have just bought a 67 dart gt---full body off restoration-- 318--large lift cam----727 with kit -----narrowed moser rear end-----runs great with the afb carb //dual plane stock intake--- but its leaking around the gaskets and maybe the rods also-----elderbrock 600 or 750 performer is 20% off online at advance auto parts now with 25$ elderbrock rebate also-------will these carbs work well with this motor ? i dont race, just a little goose now and then on open roads------your thoughts please---thanks
