I don't see a high temp loctite available. There's a blue (removable - 242) and a red (high strength - 271). Both are advertized for automotive use with a service temperature up to 300F.
I used the 242 when I had my bolts replaced...so we'll see if there will be any trouble with them loosening in the future. Didn't want to go with nordlocks because it was smaller (in diameter) than the OE washer - I wanted more "clamping" surfaces on these bolts.
