Since it was recomended to use the ARP lube or oil on the threads, head and washer, I couldn't really use loktite. I've had it on and off a couple times and I torque the pulley first with a used stock bolt to 240 lbft. then the the ARP bolt to 240 lbft., It won't come off .

I went through this also, no specifications with my bolt. Per ARP, 190 lb-ft with ARP Moly lube on the threads and the head of the bolt.
If you go to 240 lb-ft, since ARP uses 75% of material yield as thier bolt preload, you run the risk of yielding the bolt and it either breaking during installation or later during removal.
