heads

Well I would like to have the aluminums just for weight,I do have a set of J's,maybe 72's in the basement,with .050" off the face a good 5 angle valve job port matched and light blending wouldn't these flow as good as untouched eddys.I seem to remember reading this in another post.Everyone seems to have a strong opinion on which way to go on this and I can only afford to do this once.
