Whats goin on guys?? Have any of you ever used a chevy head # 14101083?? Im trying to figure out if they are worth using. I have had them sittin in the basement for a while now and if I were to use them it would be on a pretty much stock engine but only if they are worth using. Does anyone know the flow specs on these. Im wanting to know if these could make some decent numbers. There are tons of engine ID sites but I never can find info I need. Any help is much appreciated..
