East-Central Ontario
Difference as I understand it is that 60 H (yes for heavy) is regular 60 chain but made with side panels made from the same stock as the next size higher chain. So 60 H is 60 sized but the sides are made from the same material as regular 80 chain.
The masters are different. I THINK a 60H master will work on 60 but not the other way. Memory could be wrong on that though.
