3ac versus 4ac
I know you guys mainly deal with 4ag motors but I have one question which I can't seem to find the answer for. Is the head on the 3ac and the 4ac the same? are they interchangeable? Let me know if you know the answer. I can't figure out how to post on the club4ac website. thanks! Wave

We can see different bore size but there were rumours that 4AGE head can fit even 2A block (not tested in person unfortunately)...
