To be honest with you the 24's are going to be an over kill without heads and an intake. Your 19's flow plenty for your app now. I mean if you have the adjustable FPR you would be turning it down with the 24's so low to not run rich it would be like 19's anyway, but it is good if you are planning an intake and head swap soon. But it is better to have too much than not enough.
