FOXLAKE can make factory one flow really well. You can either send them yours and have them ported or exchange them. I would just have yours ported. That way you know what you are starting with. Not some heads that someone beat the shit out of. Shooting a shit load of nitrous throw them for example or shaved them to get more compression. http://www.foxlakeracing.com/mod2.php
