slant 6 engine questions

its getting replaced. I just ordered a Cloyes timing chain kit. I have always had good luck with that brand. The Rollmaster is a little too rich for what I need.
The B/RB bolt is the right one to use if You want to leave one in, the A one is too long unless You've added something to the dampner face.
Honestly all this talk of bolts & washers for the $ spent is foolish, Harbor Freight & others offer installers so reasonably priced for the hobbyist, it makes no sense to not use the proper tool.
