should i use a particular kind of thread lock when reinstalling my flywheel and counterweight bolts?

i found some with a trque rating of lik 370lbs but its temp rated to only 300 degrees f.... i've found another that has a temp rating of 450 degrees f but the torque rating is only at like 250.... what do you suggest?

thanks guys

I've always used Loctite 243 (blue) and never had a problem.
