Default Head bolt over torque

Well accidentally torqued my final head torque on my TC 96B to 22 ft lbs. instead of 17. no 1/4 turn index .Anyone done this before and not had issues?
Concerned about stretching my studs or blowing out my fire ring .

Usually theres a range for the torque. If so, are you outside that range with the 22 ftlb?

If you didn't add the 90° turn yet, loosen and torque to 17, then + 90°

In proper sequence, 120-144 in-lb. Then 15-17 ft-lb.

Then 1/4 turn ( 90 degree) If your really worried, use a dial or beam torque wrench if you have access or a free borrow from autozone and see where it goes at 1/4 turn.

You need to start over since the 17 will be at another different point on gasket thickness. That last 1/4 turn is a bolt stretch I would assume. Not sure.

Most stretch head bolts I have worked with have a helix twist in the body.

Not sure but it appears your book or head gasket says no 1/4 turn?

Not enough torgue could cause a problem.
A little over not likely.

I'd guess you talking about a head gasket form the wording.

What are you working on ??

Yeah it’s a 2011 FLSTF 96B. Just rather not buy a new head gasket set if I don’t really need to

No it calls for the final 1/4 turn but I noticed my mistake before I did the final 1/4 turn
