Default valve train noise

I bought a pond aluminum 482 with hydraulic roller 248/252 635 lift and had enough valve train noise to double check the camcard for hydraulic on it. My other engine is flat tappit hydraulic at 610 lift and seemed much quieter? Qlso is a ultra hp 750 big enough? My 470 came with a BG modified 950cfm holley. Thanks
