You might try a Helicoil kit - I believe that is an 8mm thread.

That sounds a bit high to me also. I checked the Comp website and could not find the spec - Where did you get 50lbs from?

That torque is too high for a M8X1.25 thread. You need to helicoil the head. Make sure you cover all holes in the head to keep the chips where you can clean them. Helicoils come if different lengths. Get a "2D' length if you can find it as it will be much stronger.

As for the stud torque, checked with the Crane rocker installation instructions that were developed by Vinci performance. The torque they use is 22 lb-ft. Here is a link to their instructions: Link
