I would use red locktite. I think the bolts that came with the sfi flexplate should have some type of loctite on them. My TCI bolts do. But I'm going to try the tape loctite.

Rule of thumb....if it goes into steel loctite is fine, if it goes into aluminum, anti-seize is right. Since the crank is steel then loctite is cool. I tend to use the blue medium strength for most things. Never had a bolt back out using that.

THIS... Red locktite just makes for having to use heat to remove it safely and not break bolts. I wouldnt use heat on any internal engine parts... Blue locktite is alot stronger than most think if the threads are clean of oil when applied.

I didnt put any on my crank bolts. I actualy didnt think about it. They were all pretty tight threading in hopefully it will be ok. I did use blue loctite on tc bolts though.
OP if I was you I would use blue.
