Holley 600 dp jet help

Hey all, I dropped a 600 dp on my 273. I think the secondaries are a tad to big for it. Runs great off the primary which are 66's. But rolling into the throttle it seems to big and I get a raw fuel smell after. The secondaries are 72's and the carb is all tuned out with a vacuum gauge so I know I'm good there. What jets should I throw in the back? Thanks all.
