ok i am looking at a set of edelbrock 60229 castings for my project i am working on. they seem to be the same as all the other edelbrock heads i have looked at except these dont have the steam holes drilled.. and i was curious exactly what they are referring to. i was thinking it might be the ports that ffed the egr ?? but wasnt positive. also the car they are going on has absolutely no emission equipment and is using a trick flow intake, so would these work or should i get the ones with steam holes ?? thanks
