Head gasket getting oval?

Isnt 100 lbs with arp lube too much. Over torquing the bolts fatigues them.Whats the recommended torque value?Also the aluminum heads nead a different finish than steel heads to give the gasket bite. Also check insite the head chambers for any signs of contact. Maybe contact is unloading the head causing the gasket to move.

The figures that I got from ARP for use with their studs is 100 lbs. So no, I don't think that's over torqueing, especially with studs as they don't stretch the way bolts do. It is interesting that the cylinder head manufacturer tells you to use one spec, the gasket company another, the fastener company something else. Whom do you listen too? In this case I say the fastener company. If I remember correctly Cometic's spec's are the same or close to the 100 lbs. I still say; go Cometic!
