Cylinder Studs

Hey! All the Techs out there...
Working on a 2007 1200 Sportster...Head gaskets have blown on me twice - Cylinder/Heads are not warped. Using factory head gaskets. Gaskets are blowing on left side "small bolt" side. Im begining to think the Cylinder studs & head bolts are weakening on me. When installed i can slighty see a gap which i know is no go from the begining - installing the heads correctly is being accomplished same with removing them.
Just wanted to get some more insight on the possibilites of having stretched studs? Its looking to be my last option. Any tech help would be much appreciated. Thanks

O ok cool deal thanks for the info on the gaskets ill check them out - Should i maybe replace the head bolts? It was just strange to see the head not even flush with cylinder after everything was torqued properly. I have a service manual so i did sequence right. By saying set a 10/20 u meaning ft lbs? Should i lube the studs with a small amount of oil?

Yes 10, 20 are ft/lbs.
A dot of lube is always a good idea, as better accuracy will occur.
