Stan: I was wanting to know if anyone has tried the AA heads because according to the Hoffman website their head castings come from AA Performance because the AMC heads starting having quality issues.( I just pulled a pic off of a search of images of type 4 heads that had porting work.) I was curious how the finished heads from AA ran in case we have to wait too long from Hoffman. What I got from Samba was a bunch of advice and criticism I didn't ask for or want and not anyone that answered my simple question. I made myself stop replying and haven't been back. I forget how good we have it here on SOC even with our small issues, it is still much better then most car based forums.
