Help!! Edelbrock 600 CFM Carb Problem!

I don't like Eddy carbs. Never had any good experience with them. Had three different Eddy carbs and tried them on my motor. 500 cfm, 600,and 750 all tuned up ready to go. Then I bought a 750 Holley HP carb and son of gun runs great. Might be me but it seems to me the Eddys get really hot compared to Holleys.
