How do I get rid of "spark knock"

I finally got my truck running a 7 out of 10. After a fresh carb rebuild, new HEI dist, new spark plugs. I run premium gas all the time. When I get on the gas it sounds like the the motor is going to fall apart. Just in conversation people tell me "that's a timing issue". How do I fix this? can I just advance the dist or retard?
