go 1.800.and don't go to "any machine shop" or porter that will simply open the port to match.when ever opening the port opening there must be other changes done down the port to get it right,granted in your case it would be minimal changes,but still need to be done

We offer 2 Stages of S&S port modifications, both include opening the intake runner to 1.800".
