Which is why ARP came out with their own lube and directions to use only on one side of the washer so tq is not affected.

Getting that bolt out... I'd get a good easy out extractor set. Name brand, made in USA... ie snap on, matco....

A bolt, with no head on it, has hardly any tq holding it in. The threads are in a bind. They are being pulled up. So.... follow the instructions in the extractor set to drill into the bolt while it is still in thread bind. Once you get that hole started...take a punch and punch down with a sharp rap to help unbind the threads. They are being bound up... tap down. Then use the extractor to grab into that hole started and spin it out.

If you approach it like that and stick with it...I bet you'll get it out. People think a broken bolt has tons of torque on it.... but with no head, it virturally has none. Just the little bind that the threads are in. Once you tap down to unbind the threads.... it'll spin out. Which extractors are good at grabbing and spinning out. Shouldn't have to retap the threads. Avoid the temptation to go crazy with a big drill bit....stick with the extractor until it spins out.

Excellent advice!
