ok if i get wbody stores cnc heads w/1.9.1 rockers and a 3.4" pulley on my headered setup could i just tell reptile thats what im getting and he'll be able to make me a bad a tune for it??? or could i just get a canned tune... or a custom tune from overkill... i dont have the time to custom tune having kids and all... and if i do custom tune could i make enough power to rule out getting rockers???
