Head Studs Won't Torque

[36tbird]

Mine on the 8BA in my '36 pickup are the same way. I figured it was because I chased the threads with a regular tap when I was cleaning everything up. That was before I learned not to do that on this forum's predecessor. And yes, I run studs on my 8BA because I want to.

I put shoulder washers on my builds and torque to 50. Re-check annually.
