So I just installed my mls head gasket with my arp head bolts. One of the bolts was just a 8.8 grade hex bolt which broke when torquing the bolts down. I torqued all of the bolts down to 90 got half of the bolts to 110 until the hex bolt snapped. So I just ordered oem head bolts from auto zone and I was planning on torquing them to 90ft lbs so It would better my chances of it sealing. Or can I just do 72 ftlbs because it's a mls gasket? The reason I was missing the arp bolt is because it was bent for some reason when I removed the head a year ago.
