Will put this in the GTO section. But, since #18 heads did not come on a GTO, I'm also posting the ad here.

I'm trying to help a guy find a good set of #18 heads.

As most know, these came on 1968 350HO engines.

Can't use 'em if they've been ported. Just need some good rebuildable heads, for a reasonable price.

Must be willing to ship.
