My opinion is that you should have ASKED for opinions before you bought those injectors, LOL. For that combo, 19 lbrs. would probably be the ones to stick with honestly. I'd ditch the 30 lb. injectors, and matched MAF and just pick up a different MAF for the 19 lbers. If you will be getting different heads (besides the ported stockers) sometime in the future, you may want to go with 24 lbrs instead.
