lonsomecrow and everyone else,
A 'boxed-end' wrench is all you need to tend to the cam chain tensioner, just "snug"! They aren't going anywhere!
As to the twisted off / almost twisted off cam bearing cap bolts, get the original equipment or at least flanged / shouldered bolts!
And by any means, Purchase a proper 1/4" drive 50-200 INCH pound torque wrench!
Doo-Hickey lock bolt, 69-80 INCH POUNDS for instance!
Bigger bolts one can 'quess-at', it is the little ones that get you in trouble.
Modify at "YOUR OWN RISK"!
