ACH heads?

[brock1949]

I just picked up a couple sets of heads from a guy who parts 6.5s and one of the sets was off a 300K commercial truck that had clearly been recently rebuilt (2-5) years maybe tops. The heads had ACH cast into them and no one so far has know anything about them.. good bad etc.

Best i can figure is alabama cy head co but no one knows if they ever made a 6.5 head. These are LARGE 1" tall letters maybe.

Thanks!
