true on the harlands but there's are more of an orange color. and I have never seen an unmarked harland rocker. these are more redish purple color. and yea I will trash the rest of them. I need a new set and dont know who I should go with and I dont even know what ratio these are. I want to find some one who needs a nitrous kit for a holley carb and has an extra set of rockers !! any takers competion cheater NOS kit all new thanks jessie
