I agree with this on the cloyes, they make the majority of chains now and they are less than impressive. My advice is to either use a summit billet chain ( just a cloyes like everything else but cheaper) and a tensioner or go with a pro gear chain, hughes sells them and it may be worth your time just to call them. The chain tensioner is like discussing politics around here but I will say our group has several of them in engines with zero issues and a lot of street time.
