You're fine. The sequence is important. The three step torque sequence is important. The end torque is the goal, and you said 80 ft/lbs. That's important. I wouldn't try to make 350wHP on it, but you're fine anyway.
Do it once. Do it right. If it fails from here on out, it's because you did something else wrong, not your head stud torque.

Just blew my head-gasket 25 psi cometic head-gasket arp head studs. So i don't know it was all installed correctly i guess ill take it apart and find out what the problem was. Has anyone else had problems with cometic head-gaskets? Thanks.

The factory head gasket has proven over time to be the best option. The Cometic brand works well in various applications, but there had been issues in the past with the 420a version.
